Pressure Compensator

Series LCM

Characteristics

2-way pressure compensators series LCM are sandwich

plate valves designed for stacking beneath a proportional

directional control valve with a standardised mounting

pattern.

The valve maintains a constant pressure differential

between ports P and A or P and B across the directional

valve. When the cross sectional opening of the directional

valves is held steady, a constant ﬂow rate is achieved,

regardless of consumer load ﬂuctuations.

The control pressure applied to the spring side of the

compensator spool is supplied from port A or B via a

shuttle valve. Flow rate regulation is automatically effec-

tive in the port with the highest pressure.

Proportional DC valve model D31FS with 2 way pressure compensa-

tor LCM3 maintains a constant ﬂow rate.

The diagram shows the design according to code X.
