SSVSpecial Compensating Bypass Check Valve

Range of Applications Compared to the series SSV 10-12, the series SSV 18-20 uses an integrated non-return valve in the bypass. It automatically protects centrifugal pumps – especially those handling hot water – from damage which might occur through partial evaporation of the water content during low load operation.As soon as the pump capacity drops below a pre-determined flow rate, the bypass valve opens sufficiently to maintain the pump minimum flow rate. This rate is maintained even if the flow through the main valve to the boiler or process is completely shut off. The pressure will be reduced by integrated throttle stages within the bypass.The type SSV 20 is supplied with a larger bypass.

This is required for larger bypass flows up to 40 bar differential pressure. The choice is done in our works.The valve range SSV is utilized for fluids with a viscosity < 150 cSt without solids, e.g.:• in boiler feed water and cooling water plants• in Petrochemical and Chemical Industry and refrigeration• in potable water supply and backwater disposal • Offshore• in snow production• in steel production• for fire fighting systemsThe utilization in nuclear power plants emphasizes the reliability of these fittings (certified to KTA 1401).

The Compensating Bypass Check Valves of the range SSV 18 can be utilized for Δp up to 220 bar, the type SSV 19 for Δp up to 250 bar and the SSV 20 for Δp up to 40 bar with temperature ranges from - 250°C up to + 400°C. The valves are manufactured in the sizes DN25 to DN500 and the range of nominal pressure is PN 10 up to PN 400 (ANSI 150-ANSI 2500). The bypass flow can be up to 50% of the main flow, recommended is up to 35%. The valve operates without additional auxiliary energy.For the protection of fluid pumps with delivery heads of above 2200 m we recommend the range SMA 63/64 (see prospect) with “ON/OFF“-regulation of the bypass.

Mode of OperationThe Compensating Bypass Check Valve is flow controlled, that means the non-return cone (3) is kept in its operating position by main flow only. The valve is designed in such a way, that the cone reaches its utmost upper position at denominated main flow.The non-return cone activates the Rotary Slide Valve (13) in the bypass by means of a lever (14). If the cone is positioned on the cone seat, the Rotary Slide Valve is completely open. It closes corresponding to the rising of the cone by delivery in main direction. The valve just allows such an amount of bypass flow, as it is necessary for supplement of the required minimum flow of the pump.As soon as the main flow exceeds the minimum pump flow, the bypass closes. On the other hand the bypass opens again, when the main flow falls short of the bypass flow.

InstallationValves SSV should preferably be connected directly to the pump discharge branch, and must be mounted vertically with flow entry from below. Limited possibilities for horizontal installation exist, but must be confirmed by the manufacturer.The bypass flow is piped back to the suction tank.

All bypass valve components are easily serviced. To facilitate serving of the bypass valve, we recommend a removable flanged pipe approx. 1 m long to be fitted to the bypass branch. We also recommend to install a pressure relieve valve and a stop valve. The stop valve must be of a type which can be locked in the “OPEN“ position.Illustration 1 shows a typical arrangement and flow scheme of our Compensating Bypass Check Valve. The hand-operated bypass feature is optional.In order to avoid vibrations in the valve and the pipes we recommend continuing the connecting line at the outlet (DN2) and Bypass branch (DN3) for approx. 2-3 m in the chosen nominal size. A pipe bend directly at the bypass branch is not admissible.

Illustration 1: Bypass Return with additional hand operated branch (optional).


DesignThe construction is according to specification AD 2000 and particularly to EN 13445. As per Pressure Equipment Directive 97/23 EG the products are provided with the CE marking and the Declaration of Conformity. Certified according to the Module H1 (Pressure Equipment Directive 97/23 EG) all dangerous material classes of category 1 to 4 are covered. Suitable nominal size and nominal pressure are to be chosen according to the pump pressure branch. However, it must be observed, that the admissible flow velocity of 10 m/s may not be exceeded (guarantee). Compensating Bypass Check Valves in larger sizes, for higher pressures and in special designs, which are not listed here, can also be supplied (on request).If the bypass flow has been indicated too low, it may result in vibrations within the plant, a hammering Compensating Bypass Check Valve resp. a damage of the Valve and the pump (see “inquiry specifica-tion“).

ConstructionThe Valve SSV comprises a radial split body with non-return cone (3), and a separate bypass device in the bypass branch.All sliding parts are machined from proven stainless steels suitably matched to each other. Parts subjects to wear such as the check valve seat are stellite-faced. The coil springs are also made of stainless steel. In the standard version the casing is of forged steel P250GH (1.0460). In addition high- quality steels of various qualities can be supplied. In the Bypass the minimum flow is passed off automa-tically by the Bypass valve head (12). The pressure

reduction from pump pressure to the counter pressure in the bypass line takes place via the Bypass Valve Head (12), the throttle (16) and the valve (17) for type SSV 18-20.

The hand operating branch with multiport-throttle is fitted at the casing below the cone seat and serves to pass off the minimum flow via a hand-operated valve combination. We recommend the branch for protection of the internal bypass parts at ex-treme operating conditions, e.g. at high differential pressures and frequent operation in the range of by-pass flow as well as for filling and start-up of the plant.

Start-Up-Trim (SUT) substitutes the Bypass valve head during cleaning and start-up of plants and therefore spares the sophisticated regulating parts (optional, permanently open Bypass outlet). Also usable instead of the Hand operating branch.

Warm-up branch, pressure gauge branch, draining branch etc. can be provided, if required.Flange designs to DIN, ANSI, BS, ISO and all related standards are possible.

Furthermore we supply:• Compensating Bypass Check Valves with control disc and bearing plate in the bypass for high bypass flows at low pump pressure• Autonomous Minimum Flow System Type SMA 63/64 from DN65 upwards at pump pressures from PN 250-400 bar.• Multiport throttles for pressure- and flow reduction of high-pressure media from DN15 upwards and pressures from PN 10 to PN 640 bar.
