Pressure regulating valve
The pressure regulating valve (reducing valve) is used to control the pressure applied to the flow so that it will be constant during flow control. Various types of valves are used according to application, as explained below.Pressure regulating valves are classified into general reducing valves and backpressure valves, and are represented by the symbols shown in the figure. The reducing valve controls the outlet side pressure so that it will be constant when the supply-side pressure changes. It is frequently used in the initial stage of a system. Meanwhile, the back-pressure valve is a kind of continuous flow relief valve that removes gas to keep the primary-side pressure constant.The reducing valve controls the outlet-side pressure, and a pressure gauge is provided on the outlet side. The KOFLOC 6600 is equipped with a pressure gauge port, and a pressure gauge is connected to the port in such a case. The pressure at that port is practically equivalent to the outlet pressure; therefore, the pressure gauge can be connected to the outlet side.
Flow characteristics of regulating valve
The flow characteristics graph of a reducing valve shown in the cata-log is based on the flow sheet shown in the figure. In the example graph, the primary pressure (supply pressure) is 686 kPa. In the suc-ceeding stage of the reducing valve, the secondary pressure is set as a load resistance by a regulating valve when the valve remains closed (0 flow). This value is the flow 0 in the graph, namely, the value at the left end. Then the needle valve is opened to let gas flow, and the change of the pressure (secondary pressure) that is set accord-ing to the flow is plotted. The state in which the set pressure does not change is ideal, but because of the characteristics of a reducing valve, there is some influence up to a certain flow, and the pres-sure will change when the flow reaches the limit. This area where the change is minimum is the area where reducing valves should be used. In the case of a backpressure valve, the primary pressure is the set pressure. The way to understand the flow characteristics graph is the same as that for the reducing valve.
Example: In the case where the set pressure is 294 kPa when the primary-side pressure is 686 kPa in the example graph, the characteristics are satisfactory if the flow is below the ○mark in the figure, but the pressure characteristics dete-riorate when the flow exceeds 11 l/min. Use the valve at a flow rate below 11 l/min.
Pressure characteristics
In the case of a reducing valve, the pressure change on the second-ary side, when the primary-side pressure on the aforementioned flow sheet is changed, is shown. The control characteristics differ slightly depending on whether the primary pressure increases or decreases, and the changing condition is shown by the arrows.

Tips on selection
#6600, #6610 are panel-mount type high-precision regulating valves. #7700 are for cylinders. #6600 is used for analyzers and others for control of comparatively small flow. #6700 are used when the flow is large. #6610 is a diaphragm type for low-pressure setting. #6600, #6700, #6610 are diaphragm type regulators.Models #6800 and #6801 are backpressure valve and their applica-tion is different from that of other regulators.#7700 is a regulator equipped with a flow meter.

This valve has been developed for better repeatability and quick, reliablepressure regulationby increasing theac-curacy of the low-pressure side compared with the Model 6600.It is ideal forhigh-sensitivityanalyzersandsemiconduc-tor manufacturing equipment, as well as for research and development.
Features
•High-precisionregulationonthelow-pressureside High regulation performance with repeatability of ±1% or less when
the pressure on the primary side and load resistance on the second-ary side change under the set pressure condition of 0.01–0.15 MPa.•Non-greasespecification The sections in contact with gas are made of stainless steel, Viton,
and Teflon without using grease. This valve is ideal for the semicon-ductor industry which requires ultra-clean conditions.•Locknut The regulating position, once it has been set, can be fixed by a lock
nut to prevent the setting from changing.•Non-bleedtype This non-bleed type valve prevents gas from leaking to the outside.
