Pressure relief valves

DeepSea Power & Light products have earned a reputation for reliability in the most challenging environments and the latest pressure relief valve (PRV) is an excellent example. This adjustable PRV incorporates dual O-rings for maximum protection against leakage. The new PRV has the standard SAE J1926-1 Straight Thread O-Ring port in addition to the existing standard 7/16-20 threaded holes. The base of the new Dual O-ring Pressure Relief Valve is equipped with hexagonal sides for easy installation with a standard wrench and the valve stem incorporates a hex socket for adjustment without the need of a special spanner tool. The head of the valve stem can be flat or curved with a finger slot for manual operation/venting.
