ExplanationsThe hydraulic pump for open loop applications is equipped with two main ports: A suction port and a high pressure port. The

suction port is connected to the hydraulic tank, the high pressure port to a manifold valve plate (directional control valves). When

the hydraulic pump is driven, it draws hydraulic fluid out of the tank. The fluid circulates always from the hydraulic pump to the

manifold valve plate and from there through lines to the corresponding actuators, like hydraulic cylinders and /or hydraulic motors.

The pressure relief function limits the pump pressure on the primary side (primary relief / cut-off). Flow direction and velocity of

the oil determine the direction of movement and speed of the hydraulic cylinders and the sense of rotation and speed of hydraulic

motors. Then the hydraulic fluid flows back to the control plate and from there usually through a cooler and filter into the tank. In

addition to the main ports, hydraulic pumps and motors also have filling, ventilation and leakage oil ports. The leakage oil from

hydraulic components flows through separate lines back into the hydraulic oil tank. If the hydraulic oil tank is not pre-pressurized, a

venting filter must be mounted on the hydraulic tank to ensure that no contamination can enter from the air into the tank.

The LSC system

The Linde Synchron Control (LSC) system is a Load-Sensing (LS) valve system with downstream compensators (post compensated).

The LSC system for open hydraulic loops enables pump flow to be controlled by the flows required by the function, based on the

load sensing technology (LS-technology). In an LSC system the effect of changing loads, a changing number of functions and

varying load levels on different actuators is compensated.

The LSC system in general works with a constant differential pressure (∆pLS) at the measuring orifices of all of the differentdirectional control valves. With this the control quality, especially in the partial control range, is independent of the effective load

pressure on the actuator, because the flow remains constant, even under load changes. The regulating LS pump responds to flow

requests of the valve and automatically provides the required f low, irrespective of the load pressure needed. „Load-Sensing“ means

that the regulating LS pump „feels“ the LS signal as high pressure from the actuator with the highest load pressure.

The LS pressure is generated by the pressure copier in the compensator of the directional control valve with the highest load

pressure. The pressure copiers also select the highest LS pressure. The LS signal feedback travels from the LSC valve block through

a pressure line to the LS port on the pump. This is the only external signal required to control the pump flow.

The ∆pLS is the difference between pump pressure and LS pressure. With short-term changes in load pressure (LS signal), the

∆pLS also changes instantaneously. The pump responds by instantaneously changing its displacement, until the ∆pLS returns to a

constant level.

Optimal functioning of the LSC system is ensured in combination with Linde regulating LS pumps. The absolute pump pressure

value has no essential effect on the function. The pump automatically compensates for fluctuations in drive speed by adapting its

displacement accordingly.

Due to the post-compensation the LSC valves are able to maintain synchronous controllability of several actuators, even under

excessive system demands. If the sum of all consumers demands more f low than is available, there are excessive system demands

or saturation. Under such operating conditions the flow distribution ratio for the individual actuators is maintained. As a function

of the flow shortage the ∆pLS drops accordingly. All actuators automatically keep their full proportionality to each other with only

a reduction in cycle speed. This reduces the requirements on the machine operator, because control lever readjustments, as are

common with other systems, are not required. The LSC system enables the realization of highly efficient hydraulic systems, which

are strictly machine function oriented.

Our application specialists are looking forward to assist you in the individual layout of your machines.

LSC Manifold valve plate system VT modular

The product range VT modular is a uniform modular designed manifold control plate system for open loop hydraulic applications

based on the proven LSC valve technology.

The series VT-01 C25-32 combines directional control valves for the control of hydraulic actuators with supply flows of up to

600 l/min at pump pressures of up to 400 bar with valve manifold plates to provide the common infrastructure.

Having one pump path and two return flow paths with streamlined cross-sections of 32 mm each, the power infrastructure is

generously sized. This ensures low-loss transfer for pump flows of up to 700 l/min and return flows of up to 1000 l/min.

The innovative, fully modular system enables the arrangement of manifold valve plate systems with maximum 12 directional control

valve functions – for any conceivable valve technology applications in open loops within the described range of capacity. The

standardized interfaces

>> IF32 (Interface nominal size 32)

>> CF25 (Common Footprint nominal size 25)

>> SW18 (Sandwich nominal size 18)

enable free arrangement of the individual valve modules of the control plate and simple extension in already installed manifold

valve plates based on the series VT-01 C25-32. The functional modules themselves are also freely configurable.

System components. VT base plates

The VT base plate is the basic element of this modular system. It provides the basic infrastructure to supply the power and signal

paths for all attached directional control valves and base plate extensions. Depending on the design further basic functions can be

integrated in the VT base plates, such as the complete pressure relief for the hydraulic system.

The VT base plates have various type dependent interfaces. These can be used to connect directional control valve modules andinfrastructure modules.

>> The CF25 interface provides for the direct attachment of subplate mounted directional control valve modules of Linde series

VW-01. The CF25 interface connects in parallel into the infrastructure provided by the VT base plate. The CF25 interface has been

designed for valve supply flows of max. 600 l/min.

>>The SW18 interface is used for the direct attachment of max. three directional control valve modules of Linde series VW18S-01

in sandwich design. The infrastructure provided by the VT base plate is passed through each of the directional control valve

modules. The SW18 interface has been designed for valve supply flows of max. 230 l/min.

>> The IF32 interface serves as a continuation of the infrastructure channels in the VT base plate by means of infrastructure

modules. Those have CF25 and SW18 interfaces. Further directional control valves with CF25 or SW18 interfaces can be

connected to these interfaces. The infrastructure modules may contain further infrastructure functions. The IF32 interface has

been designed for pump flows of max. 700 l/min.

System components. Base plate VT4-01 C25-32 H

The base plate VT4-01 C25-32 H, hereafter referred to as VT4, is designed with three CF25, one IF32 and one SW18 interface. In the

maximum configuration this allows for a combination of manifold valve plates with up to twelve directional control valve functions.

>> Three subplate mounted directional control valve modules directly on the CF25 interfaces of the VT4

>> Maximum three sub plate mounted directional control valve modules on infrastructure modules, which are directly connected to

the IF32 interface of the VT4>> Maximum three sandwich-type directional control valve modules directly connected to the SW18 interface of the VT4

>> Maximum three sandwich-type directional control valve modules connected to the IF32 infrastructure modules

The VT4 base plate has the following integrated functions

>> LS pressure cut off (LS-PCO) with optional remote control of the response pressure (Remote LS-PCO).

>> Unload valve (opens the pump path to tank when the ∆pLS is exceeding 45 bar)

>> LS drain (relieves the pressure in the LS line when no directional control valve is activated)

>> Automatic bleed valves for the hydraulic actuation of the CF25 directional control valve modules.

With LS-PCO remote control option: 160-330 bar

LS pressure cut-off (LS-PCO) LS-PCO remote control (optional)If the option «LS-PCO remote control» is selected at the order,

the response pressure of the LS pressure cut-off (LS-PCO) can be

raised by the amount of the pilot pressure level (usually 30 bar)

applied to the DHS port.

If the option is not ordered, the sealed metal plug on the DHS

port must remain closed.


12/5212


The base plate VT1-01 C25-32 H, hereafter referred to as VT1, is designed with one CF25 and one IF32 interface. The maximum

configuration allows for manifold valve plates with up to 3 directional control valve functions.

>> One subplate mounted directional control valve module directly on the CF25 interface

>> Maximum two subplate mounted directional control valve modules on two infrastructure modules, which are directly connected

to the IF32 interface of the VT1

Apart from the automatic bleed function for the hydraulic actuation of the CF25 directional control valve modules, no further

functions are integrated in the base plate of the VT1. For this purpose one must always add a pressure relief module on the IF32

interface when creating an independently working VT1 based control plate.

The VT1 provides four M12 threads for mounting purpose.

If the application requires the combination of a VT1 based control plate with a VT4 based control plate, the pressure relief function

of VT4 can be utilized through an external plumbing. In this case the VT1 does not require an IF32 relief module.

System components. IF32 infrastructure modules

Infrastructure modules can be attached to the IF32 interface of VT base plates series VT-01 C25-32 to provide additional subplate

mounted and sandwich-type directional control valve modules. Depending on their design, VT base plates can be fitted with max.

three infrastructure modules connected in series per IF32 interface. IF32 infrastructure modules with CF25 interface always contain

the automatic bleed valves for the hydraulic actuation of the CF25 directional control valve modules to be assembled.

The following IF32 infrastructure modules are available>> IF32 infrastructure module for CF25 subplate mounted valve module

>> IF32 relief module

The IF32 relief module (with threads to mount the assembly on a bracket)

contains basic functions to protect the hydraulic system:

– LS pressure cut off (LS-PCO) with optional LS-PCO remote control (Remote LS-PCO)

– Unload valve (opens the pump path to the tank when the ∆pLS is exceeding 45 bar)

– LS drain (relieves the pressure in the LS line, when no directional control valve is activated)

These functions are integrated in the VT4. Should the application require the operation of a manifold valve plate based on

the VT1 base plate without being connected to a protected system, the use of an IF32 pressure relief module is mandatory.

Characteristic of the relief function, see base plate VT4.

System components. LSC directional control valves series VW-01

Directional control valves series VW-01 serve the purpose of dividing and controlling the supply flow fed through the infra-

structure of the VT base plate to the different actuators and the return flows from the actuators. Based on the LSC technology they

are designed as LS valves with a downstream compensator and a pressure copier individual for each actuator side. Compensators

and pressure copiers are integrated in the hollow control spool design.

The individual selection of compensator and pressure copier per side enables optimal matching to the application and ensures ahigh level of flexibility and functionality.

The compensators compensate the system pressure down to the actuator load pressure and maintain the pressure drop over the

control edge of the control spool (measuring orifice) at a constant level, until saturation is reached. At the start of control spool

piloting the compensators open the path between pump and actuator only after the pump pressure has reached the load pressure

level. This ensures that a function will not drop off when being actuated under load.

PilotingIn all directional control valves series VW-01 the control spool is held in centered position by centering springs on either side.

They are supported inside the control caps, through which the hydraulic pilot pressure signals are fed to the faces of the control

spool. When a hydraulic pilot pressure signal is applied, the control spool is moved out of neutral position in accordance with the

characteristic of the centering spring, whereby one work port of the valve section is opened to the pump path, while the other

work port is relieved into the return flow passage.

Depending on the pilot pressure controller (control lever) two pilot pressure ranges for LSC valves are available:

>> Standard: 6 to 25 bar

>> Alternatively: 6 to 19 bar

With respect to their characteristics, directional control valves series VW-01 can be side selectively configured according to their

individual targeted application.

>> Control spool characteristic

Various control spools with matched compensator/pressure copier combinations:

– Symmetric control spools for rotary actuators (motors) and synchronized speed cylinders (control spool S1x/S2x)

– Asymmetric control spools for differential cylinders (control spool A1x)

>> Start of function at the actuator movement function

The start of actuator movement can be selected within the specified pilot pressure range.

>> Control speed

The positioning speed of the control spool can be influenced via throttle check valves in the pilot pressure ports.

>> Control spool stroke

The stroke of the control spool can be limited by stop screws. This enables optimal adjustment of the work port flow, based on

the maximum available flow of a control spool.

>> Cavity for work port relief valves

The cavities can be used differently, depending on the application:– combined work port relief pressure relief/make-up valve

– make-up valve

– plug

>> Control cap orientation

The orientation of the pilot pressure port on the valve control cap can be altered in 90° steps.

The functionality of directional control valve series VW-01can be further modified with intermediate plates and work port-mounted

plates.

System components. CF25 subplate mounted valves

The CF25 sub plate mounted valves are designed for attachment to the CF25 interfaces on VT base plates and IF32 infrastructure

modules in three nominal sizes with the following maximum possible flows (at ∆pLS=20 bar):

>> VW18-01: 250 l/min

>> VW25-01: 400 l/min

>> VW30-01: 600 l/min

The specified flows are independent from the position of the CF25 interface on the VT base plate or the position of the IF32

infrastructure module with respect to the VT base plate, because the available CF25 interfaces are arranged parallel to the power

infrastructure of the VT base plate.

Besides the general characteristics of directional control valves series VW-01, CF25 subplate mounted valves have the following

characteristics:

>> Hydraulic piloting is possible through the pilot pressure ports on the valve caps, as well as through the pilot pressure channels

in the valve footprint CF25.

>> Automatic bleeding (obligatory) of pilot pressure lines and pilot pressure caps through the CF25 interface

(by bleed valves in the VT base plates and IF32 infrastructure modules)>> Restrictor orifice (side selective/optional)

Restrictor orificeThe two tank paths of the CF25 interface in VT base plates and IF32 infrastructure modules have a spot face to take up orifices. These

orifices increase the return flow pressure and improve the control of high return flows. This prevents cavitation in the supply side

in case of negative loads.

Orifices with diameters of 10 mm and 15 mm are available.

The following diagram helps to choose suitable orifices:

Maximum flow VW18S-01: 230 l/min (at ∆pLS=20 bar)

The specified flow refers to an SW18 sandwich valve section which is directly attached to the VT base plate or mounted on an IF32

infrastructure module. Concerning further SW18 valve sections one must consider that the maximum flow depends on their position

in the valve stack (based on the serial arrangement of the SW18 interface which is infrastructure-related. See chapter .).

In difference to the general characteristics of subplate mounted directional control valves series VW-01, SW18 sandwich valves

have the following characteristics:

>> Sandwich-type valve housing for SW18 interface, unlike sub plate mounted valve housing for CF25 interface.

>> Automatic bleeding (optional) of pilot pressure lines and pilot pressure caps by bleed valves directly in housing or valve section.

>> No restrictor orifices available.

System components. Functional modification of directional control valves

The functionality of directional control valve series VW-01 can be further extended with intermediate plates, cover plates and work

port-mounted plates. Intermediate plates can be mounted under the valve section on its mounting interface (CF25/SW18).

Work port-mounted plates are assembled after the valve section directly to the SAE work ports.

Cover plates close the corresponding interface (CF25, SW18) leak and pressure tight.

System components. CF25 plates

CF25 intermediate plates and CF25 cover plates are to be mounted to the CF25 interface.

Intermediate plates are used to generate a certain upstream function for the subplate mounted valve arranged above it. This

enables specific optimization of valve functions onto the application.

The following CF25 intermediate plates are available:

>> CF25 intermediate plate LS disabled

>> CF25 intermediate plate for regeneration

CF25 intermediate plate LS disabledWhen a pilot pressure signal is applied to ports pStA or pStB, the intermediate plate LS disabled interrupts the forwarding of the LS

signal from the subplate mounted valve to the VT base plate and adjacent valves. The LS signal transmission from the VT base plate

towards the subplate mounted valve remains active. No other signals will be interrupted.

In a multi-functional control this function makes sure that the system pressure is not determined by the load pressure of thedisabled valve section, after this section has moved an actuator against its end stop. Without this function the system pressure

would increase up to max. LS pressure (LS-PCO value). All other functions would have their flows assigned with significantly

higher compensation losses. With this disable function the system pressure is defined by the next lower function. The valve

section with disabled LS pressure still receives oil with the current system pressure. This reduces compensation losses and ensures

a pressure supply, which is sufficient for the section that has been moved against the end stop. Overall system efficiency increases,

without a noticeably impairment of the function.

Application example

Closing a grapple and holding it closed to clamp material, while extending the arm at the same time. In this case the pilot pressure

signal to extend the arm disables the LS signal from closing the grapple.

CF25 intermediate plate for regenerationWith the regeneration plate the return flow to the tank from the head side of a differential cylinder is diverted to the make-up

valve of the rod side. The remaining tank return connection of the manifold block must be equipped with a return flow throttle (see

section CF25 subplate mounted valves), to increase the return flow pressure. This return oil utilization is frequently used for

functions which e.g. retract the cylinder by gravity and in which the rod side is hardly ever pressurized or only with very low

pressure values.

The use of the intermediate plate for regeneration demands the use of a regeneration spool in the directional control valve. See

section «special spools» in chapter «System components. Control spools in directional control valves» for further information.

Application example

Lowering the boom. Very often the required flow from the pump to the rod side can be distinctly reduced to achieve a considerablegain in efficiency.

System components. Work port-mounted plates

Work port-mounted plates are mounted to the work ports of the directional control valves.

Tank bypass platesA tank bypass valve with the corresponding nominal size can be mounted to any directional control valve from Linde.

The following tank bypass plates are available:

>> Tank bypass plate 0.75“ for size18

>> Tank bypass plate 1.00“ for size 25

A tank bypass plate serves the purpose of reducing return flow pressures. The work port-mounted plate and a separate tank path

thereby provide an additional connection between work port and tank, in addition to the internal connection inside the valve. The

switching function (not proportional) is activated by the pilot pressure of the corresponding valve via the pilot signal, which also

controls the valve itself. The pilot line is routed externally to the port pst.

This option, which can be modularly mounted to each valve of size 18 and size 25, considerably reduces the return flow pressure,

thereby enhancing the efficiency of the application.

Configuration of the valve system. Structure of modular system

The modular system of the VT-01 range enables flexible and application oriented configuration of manifold valve plate systems

based on the available modules of a building-block system.

The following modules are available:

>> VT base plate

>> IF32 infrastructure modules

>> CF25 directional control valve modules

>> SW18 directional control valve modules

A CF25 directional control valve module consists of the actual CF25 directional control valve section and possibly of the mounted

intermediate plate and/or a work port-mounted plate.

The control plate system configured on the basis of modules is sub-divided into different stacks.

Stack 0: VT base plate including directional control valve modules

Stack 1: maximum three IF32 infrastructure modules including directional control valve modules,

directly mounted or attached to the VT base plateStack 2: maximum three SW18 sandwich-type directional control valve modules and one SW18 intermediate plate

on adaptor plate on stack 1

Stack 3: maximum three SW18 sandwich-type directional control valve modules and one SW18 intermediate plate,

directly on the VT base plate

Annotation concerning the stacks

>> The SW18 stacks 2 and 3 must only contain one intermediate plate.

>> The possibilities of extending the VT base plate (stack 0) depend on the design as VT1 or VT4.

>> Stack 2 and 3 are only available for the VT4 baseplate.

>> The positions of the directional control valve modules are clearly determined by the stack and the position of the module in the

stack.

up to 230 l/min VW18S-01

The maximum flow depends on the position of

the valve in the stack

(see section „SW18 sandwich valves“)

Configuration of directional control valve modules per position on the manifold valve plate in the following sequence:

>> Basic functions of the directional control valve section. With differential cylinders as actuators, the piston or head

side is connected to work port A, the rod side is connected to work port B.>> Necessary extension functions by attached intermediate plates. Only maximum one intermediate plate per CF25

directional control valve module and per SW18 directional control valve module is permitted.

>> Necessary extension functions by attached work port-mounted plate.

Mounting the manifold valve plate

Step 3:

The completely configured manifold valve plate must be fastened at the place of installation. The system components are provided

with appropriate threaded bores for that purpose. To ensure a proper fixation, screws with property class 8.8 must be used together

with the correct bolting torques.

Important note

In specific cases additional stress free bearings are required. In this case the following conditions do apply:

>> If the VT4 base plate is solely used without infrastructure modules, no further measures are required.

The control plate is fastened by the existing threaded bores.

>> If IF32 infrastructure modules are used, the customer must provide an additional stress free bearing to absorb occurring mass and

acceleration forces. Appropriate threaded bores are available in the IF32 infrastructure modules, cover plate, adaptor plate and

pressure relief module.

The user also needs to analyze the respective installation position and the application.

Information for special applications is available on request.
