Pressure compensated valve

Pressure compensated valve

The most common component with this capability is a pressure compensated flow control. These valves can operate with hydraulic system flows as high as lpm and pressures up to 4bar with the option of an integrated adjustable or tuneable reverse free-flow check valve. Parkers pressure compensated flow control valves are ideal for cylinder or motor control andor bleed-off applications within a broad range of markets, such.


This could be a needle valve or other variable orifice. The pressure reducing valve and the smothering of this valve are placed in series with each other. The valve is based on a Pressure Compensator block installed upstream from a Variable Orifice block, as shown in the following illustration.


The Pressure-Compensated Flow Control Valve block represents a pressure-compensated flow control valve as a data-sheet-based model.

Cartridge configurations are preferred because of their compact size. A pressure-compensated flow control valve has a fixed throttling flow at all pressures. At a three-way pressure control valve, the pressure relief valve and the.


Flow control valves, such as the Prince valve, help with pressure compensation.
The two-way pressure-compensated flow control valve is also called a series valve. The design incorporates a hydrostat which maintains a constant kgcm(psi) pressure differential across the throttle which is an orifice, whose area can be adjusted by an external knob setting. In a pressure compensated flow control, a hydrostat is integrated into the valve, which is a component that measures pressure drop across the metering portion of the flow control. Simply state the method for reducing interaction between functions is to dedicate a pressure-reducing, pressure-compensated flow-control valve to each four-way function.


The cartridge can be accommodated in either a subplate or a manifold with equal ease. By rotating the handle, the flow out the CF, or controlled flow port, can be varied from approximately to the maximum controlled flow allowed.

There is a short discussion on pressure-compensated flow control valves on page 13- but a valve in cutaway form is applied to a bleed-off circuit in Figure 13-10. This valve from Prince Manufacturing is a pressure compensated adjustable flow control valve.

Pressure-compensated Flow Control Valves Hydraulic Valve

A pressure-compensated flow control valve (such as the one shown in Figure 13-2) automatically maintains a constant pressure drop across the orifice. A centering ring assembly is needed between the flange and the opening.
