Compensated high flow PVBZ with POC
The compensated high flow PVBZ with POC 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 bleed-off will prevent pressure build-up on the work ports in neutral.
The Pilot Operated Check valve giving very low leakage will prevent cylinder creep.
