کانتربالانس Dual-Counterbalance / A-VBSO REXROTH

It provides static and dynamic control of load by regulating the flow IN and OUT of the
actuator, through 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 the actuator, then holds the load against reverse
movement; with pilot pressure applied at the 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 the pressure setting in all functions.
