Heavy Duty Pressure Relief Valve

The Heavy Duty Pressure Relief Valve (PRVHDNL) is engineered for superior performance in cold water systems. Factory set at 75 PSI, it is recommended for use in systems up to 150 PSI. This no-lead valve protects pressure tanks and piping from overpressure damage and is an essential safety component in residential and commercial water systems. Made with quality materials and precision-tested to ±15% accuracy, this pressure relief valve is field-adjustable by removing the cap and turning the internal disk—though doing so voids the warranty. Note that after activation, manual reseating may be required.   Key Features: Recommended for cold water systems up to 150 PSI Factory set at 75 PSI (±15% accuracy) Protects pressure tanks and piping from overpressure Field adjustable pressure (adjustment voids warranty) No-lead compliant listed and certified by IAPMO May require manual reset after activation Must be set 15 PSI above system pressure to avoid chatter and valve failure
