COUNTERBALANCE VALVES - Bosch Rexroth
apps.boschrexroth.comB – Locking of reverse downstream flow when the directional valve is not operated, or the pump is stopped. C – Load lowering metered by the piston of the relief valve opened and controlled by the pilot pressure of the “lowering” flow delivered upstream by the directional control valve, also when the load tends to overrun.

PVG 32 Proportional Valves Technical Information
www.imdl.gatech.eduPILOT OIL SUPPLY PVPC without check valve for open or closed centre PVP PVPC without check valve is used in systems where it is necessary to supply the PVG 32 valve with oil from a manually operated emergency pump without directing oil flow to the pilot oil supply (oil consumption about 1 l/min) [0.25 US gal/min]. When the main pump is working nor-
