Dual counterbalance
DATASHEET
Description
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.
