Pressure Compensated Flow Controls
Different types of flow control valves

What is a Pressure Compensated Flow Control Valve?

A pressure-compensated flow control valve has a fixed throttling flow at all pressures. The two-way pressure-compensated flow control valve is also called a series valve. The pressure reducing valve and the smothering of this valve are placed in series with each other. At a three-way pressure control valve, the pressure relief valve and the throttle in this valve are parallel to each other.

The two-way and three-way pressure compensated flow control valves are quite similar. The only difference is that in the latter type, the excess oil flow is not drained through the pump's safety valve but through the flow control valve itself. The pump pressure for a three-way pressure compensated flow control valve is always equal to the pressure exerted by the actuator plus the spring pressure.

Note that using three-way flow control valves increases efficiency because the system pressure will never be higher than as required for moving the load. With two-way flow control valves, this is not the case because the pump keeps feeding the system with oil until the preset pressure of the pump's safety - pressure relief - valve has been reached.
