Valves
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 configuration, the valve also serves as a filler cap.
Features
•
Disposable spin-on automotive type, field replaceable
filter (240 sq inches).
•
Several pressure relief settings.
•
Economic design.
•
Optional bayonet style allows mounting in filler port with
valve also functioning as filler cap.
