When handling varying loads, the displacement and speed of the load are affected. You want the relationship between the control device \u2014 for example, a steering wheel or joystick \u2014 and the movement speed to be smooth and consistent. To achieve even operation under varying loads, a so-called pressure compensator is used. The flow rate \u2014 that is, how fast the load moves \u2014 depends on two factors: the throttling area and the pressure drop across the restriction. To eliminate the effect of a varying pressure drop caused by changing loads, a compensator valve is used.<\/p>\n
<\/p>\n
The compensator valve ensures that the pressure downstream of the valve remains constant.
\nThis means that the pressure drop across the directional valve stays constant regardless of the load. The recommended constant pressure drop varies between manufacturers \u2014 SUN Hydraulics, for example, recommends 14 bar.
\nThe compensator valve is available with different springs, allowing easy adjustment between different pressures.
\nWhen the pressure drop across the directional valve is constant, the speed (flow rate) depends only on the diameter of the directional valve. The speed can therefore be controlled independently of the load pressure.<\/p>\n
<\/p>\n
If a fixed-displacement pump is used, a bypass-type compensator should be selected.
\nThis means that any excess flow is directed back to the tank.
\nThe valve type for this setup is LR*C and can be found here.

If a variable pump is used, a restrictive compensator is used.
\nThis type of valve restricts the flow without diverting any to the tank \u2014 in this setup, the variable pump itself regulates the flow rate.
\nThe valve type for this configuration is LP*C.

There are many applications that benefit from using a pressure compensator, for example:<\/p>\n
<\/p>\n
Directional valves for mobile applications often have built-in pressure compensators \u2014 for example, Bosch Rexroth RM10 and RM15.
