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 (2) 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” (1) which can feed into the full bore (C2) the flow coming out from the annular side (C1) in order to increase the extension speed. A normally open solenoid cartridge controls the by-pass flow from valve (1) and diverts it either to V1 (for low speed extension) or to C2 (high speed extension with regenerative mode).
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.
