Compensated PVB

46 | © Danfoss | June 2019
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 Compensated PVB features:
•
Integrated LS shuttle network
•
Integrated compensator
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Optional T0 facility and external T0 port
