Short Lead Time for Hot Water Ball Valve - HOW SERIES DUAL COUNTERBALANCE VALVES FOR OPEN CENTRE – Hanshang Hydraulic

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.
