PVLP Shock and Anti-Cavitation Valve
The PVLP shock and anti-cavitation valve will relieve a pressure peak to the internal tank galleries and will
furthermore suck oil from the tank to the work port to prevent cavitation. Pressure settings range: 32–400
bar [460–5801 psi].
The pressure setting of the PVLP must always be 20 bar [290 psi] higher than LS
A/B
setting in the same
module.
