The CP302-4 is a 16-size, ow control, restrictive type pressure compensator. Restrictive-type pressure
compensators are three-ported valves that work in series with a xed or variable control orice. The
pressure compensator is located downstream of the orice and is spring-biased to an open position
as shown in the example circuit. The spool “senses” the pressure on either side of the control orice
and will vary it’s restriction in order to maintain a constant pressure dierential across the control
orice, hence maintaining a constant ow rate.

Pressure Compensator
Common applications include any circuit that requires compensated ow control going
to one actuator or circuit. Pressure compensators oer the circuit designer capability to
add pressure compensation to any xed or variable orice. This ensures that ow, and
resulting actuator speed, are maintained regardless of system and working pressures
