Overview

The Model R Relief Valve is designed to relieve excess pressure in lines containing any grade of fuel oil.  It is also suitable for use with water and air.  It opens to relieve at the “set” pressure (adjustable) and closes tightly when the pressure drops.  It should be used as a safety device to relieve excess pressure and not as a regulating valve to maintain a constant upstream pressure.

 

The assembly consists of a bronze body with threaded ends, stainless steel ball, bronze disc, and cadmium plated steel loading spring with bronze spring housing.  An adjustment screw protection cap is provided.  The valve is suitable for pressures up to 300 psig at  300° F maximum.
