Pressure/Vacuum Relief Valves
PV Series
PV Series
is an economical Pressure/Vacuum Relief Valve
used to maintain positive pressure in hydraulic reservoirs.
The large filter area makes this valve an ideal choice for use
in heavily contaminated environments. The optional bayonet
type mount allows the valve to be installed in the tank filler
port, eliminating the need for an extra port. In this configura-
tion, the valve also serves as a filler cap.

replaceable filter (240 sq inches).
2.
Several pressure relief settings.
3.
Economic design.
4.
Optional bayonet style allows mounting in filler port with
