Uncompensated PVBZ with POC

© Danfoss | June 2019
The uncompensated PVBZ is intended for controlling a work function where the function behavior in
terms of flow and pressures allows dependency on the load pressure of other functions used
simultaneously.
The Pilot Operated Check valve giving very low leakage will prevent cylinder creep.
The Uncompensated PVBZ with POC features:
•
Integrated LS shuttle network
•
Integrated POC
•
Optional T0 facility
