PVLA Suction Valve
The PVLA valve is an accessory available for PVB basic modules.
The PVLA will suck fluid from the tank to the work port to prevent cavitation by the 0.5 bar spring. The
plug will ensure that when using a single acting spool, all flow returning through the work port is led to
tank.
