Description
It provides high speed cylinder extension at low pressure operation; 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 (1) which diverts to tank the flow from the annular chamber. Two pilot assisted by-pass counterbalance “fully vented type” valves (2 and 3) provide the regenerative function by feeding into the full bore (C2) the flow coming out from the annular side (C1). The by-pass valves (2 and 3) are piloted by V2 pressure and are internally vented into V1 which acts as “Tank” line during cylinder extension. For better safety and compact assembly, the C1 and C2 ports are gasket mounted directly on the actuator.
Note: for applications outside these parameters, please consult us.
