Compensated PVB with LS A/B
The compensated PVB is intended for controlling a work function where the function behavior in terms
of flow and pressures requires independency 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 compensated PVB with LS
A/B
features:
•
Integrated LS shuttle network
•
Integrated compensator
•
Integrated adjustable LS
A/B
pressure relief valves
•
External LS
A/B

•
Integrated LS
A/B
shuttle valve for float spool usage
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Optional T0 facility
