Description
It provides static and dynamic control of load by regulating the flow IN and OUT of the cylinder, through ports C2 and C1. This valve module includes a pilot assisted counterbalance (1) on the line C2-V2 for control of the full bore side of the cylinder, a check valve between V1 and C1 which allows flow into the annular side and locks in reverse direction, a pilot assisted by-pass counterbalance “fully vented type” (2) which feeds into the full bore (C2) the flow coming out from the annular side (C1) in order to increase the extension speed. The valve (2) is internally vented into V1 which acts as “Tank” line during cylinder extension. The pilot line for the valve (2) has a controlled cross-over drain for hydraulic damping.
Note: aluminium bodies are often strong enough for operating pressures
exceeding 210 bar (3000 psi), depending from the fatigue life expected in the
specific application. If in doubt, consult our Service Network.
