Compensated high flow PVBZ with POC and manifold interface
The compensated PVB is intended for controlling a work function where the function behavior in terms
of flow and pressures requires independence on the load pressure of other functions used
simultaneously.
The integrated LS
A/B
relief valve is used to limit the maximum work port build-up on the A/B-ports
individually.
The bleed-off will prevent pressure build-up on the work ports in neutral.
