Bosch Rexroth Oil Control R930007146 Dual Counterbalance - 07.06.20.51.00.00.00F

Features
 • 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)
