Pressure compensation control
A pressure compensation valve is installed to the outlet port side of each control valve to balance the
q
load pressure.
q When actuators are operated in combination, the pressure difference (dP) between the upstream (inlet
port) and downstream (outlet port) of the spool of each valve becomes the same regardless the size of
the load (pressure).
q The flow of oil from the pump is divided (compensated) in proportion to the areas of openings (S1) and
(S2) of each valve.
