Technical Information
PVG-EX 32 Proportional Valve Group
PVB Basic Modules
Uncompensated PVB
©
Danfoss | June 2019
The uncompensated 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 Uncompensated PVB features:
•
Integrated LS shuttle network
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Optional LS
shuttle valve facility for float spool use
A/B
•
Optional T0 facility

Technical specification for A/B-port
Max. continuous pressure
*
350 bar [5076 psi]
*
With PVSI end plate. With PVS end plate max. 300 [4351 psi]
**
Intermittent pressure at max. 250,000 cycles of full PVG life time cycles, with PVSI end plate. The maximum
intermittent pressure at max. 250,000 cycles stresses the need to confirm application duty cycle before proceeding
with specification. For further information contact Danfoss Product Application Engineering.
