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 one way pilot operated metering valve (2) between V1 and C1 which allows flow into the annular side and locks/controls flow in reverse direction, a pilot assisted by-pass counterbalance “fully vented type” (3) which provides the regenerative function by feeding into the full bore (C2) the flow coming out from the annular side (C1). The extension speed increment given by the regenerative function disappears when line pressure in V2 increases above the pressure threshold needed to pilot open valve (2).
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.
