Dual counterbalance
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. For better
safety and compact assembly, the C1 and C2 ports are gasket mounted
directly on the actuator.
