Technical Information
PVG-EX 32 Proportional Valve Group
PVB Basic Modules
Dampened Compensated PVB
©
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 dampened compensated PVB features:
•
Integrated LS shuttle network
•
Integrated compensator
•
Optional shock/anti-cavitation valve facility (PVLP)
