Uncompensated PVB with load drop check valve
The uncompensated PVB 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 integrated load drop check valve prevents flow back from work ports influencing
other functions.
The Uncompensated PVB with load drop check valve features:
•
Integrated LS shuttle network
•
Load drop check valve
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Optional LS
A/B
shuttle valve facility for float spool use
•
Optional T0 facility
