OPERATION:
It provides static and dynamic control of load by regulating the flow IN and OUT of the actuator, thought ports C1 and C2.
This valve module includes 2 sections, each one composed by a check and a relief valve pilot assisted by pressure in the
opposite line: the check section allows free flow into actuator, then locks the load against reverse movement; with pilot
pressure applied at line across, the pressure setting of the relief is reduced in proportion to the stated ratio until opening and
allowing controlled reverse flow. Back-pressure at V1 or V2 is additive to pressure settings in all functions.
