Raritan Pressure Relief Valve - 75 PSI

The Raritan Pressure Relief Valve – 75 PSI (model WH3) is an essential marine safety component for any vessel's pressurized water system. Protecting your freshwater tanks and plumbing lines from overpressure is crucial to avoid costly repairs from failed seals, burst fittings, and contaminated systems. This quality relief valve helps prevent such issues by venting excess pressure before it can cause damage.

Engineered with a calibrated 75 PSI setpoint, the Raritan WH3 relief valve opens to relieve system pressure when it exceeds this threshold, ensuring the integrity of your water system under varying operating conditions. Its compact design (3 x 2 x 6 inches) and lightweight construction (0.55 lbs) allow for easy integration into existing plumbing layouts without adding bulk or weight. The precision-machined seating and spring mechanism provide reliable performance in both saltwater and freshwater environments.

Boaters relying on pressurized water systems—especially those cruising for extended periods—benefit most from this valve as a preventive safeguard against tank rupture or line failure. The Raritan WH3 integrates seamlessly into standard marine water system configurations, and it is recommended to install it on the discharge side of the pump for optimal performance.
