OV-Series Standard Hydraulic Bypass Relief Valve with Flange Connections

Brand: Fulflo Specialties, Inc
Request Information
The OV-Series valve is a "Relief Valve" (RV) in a sense that the outlet pressure doesn't affect the valve’s set pressure. The valves operate off the inlet pressures only. 

The OV-Series valve is to be used when you don't want the backpressure to affect the valves opening pressure. The valve sizes from 1/2" to 2" operate efficiently with liquids of any viscosity at pressures from 10 to 500 P.S.I.

Available in screwed connection and flange, in a choice of brass, cast iron, steel or stainless steel. 

Widely used in a variety of applications, the OV-Series valves are ideally suited for all hydraulic and lubricating systems for pressure regulation and system protection. Special requirements should be referred to our engineering staff for recommendations.
Features
  • API 520 & 614 Approved
  • Chatter-free operation
  • Mount in any position
  • Suitable for continuous duty
