Dampened compensated PVB with LS A/B

52 | © 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 dampening of the compensator reaction will slow down the system thereby
removing instability. The integrated LS
the A/B-ports individually.
The dampened compensated PVB with LS A/B features:
•
Integrated LS shuttle network
•
Integrated compensator
•
Integrated adjustable LS
A/B
•
External LS port connection
A/B
•
Optional shock/anti-cavitation valve facility (PVLP)
