Uncompensated PVB
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
A/B
shuttle valve facility for float spool use
•
Optional T0 facility

Max. continuous pressure
Max. intermittent pressure
Max. rated flow
350 bar [5076 psi]
*
420 bar [6090 psi]
**
125 l/min [33 US gal/min]

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.
