A Hubbell Heaters VRTPBNZ-075-NMF-5-150 Relief Valve releases excess temperature and pressure to safeguard the heating and cooling unit.
The relief valve protects the HVAC system by releasing excess temperature and pressure so the unit can operate within safe limits. Its 3/4 connection, 150# rating and lever-handle actuation provide the proper fit, response capability and manual testing access needed for dependable performance in heating and cooling equipment.
The relief valve may need replacement if the heating and cooling unit shows repeated pressure discharge issues, inconsistent relief operation or difficulty maintaining normal operating conditions. Physical signs can include corrosion, mineral buildup, leakage around the body or outlet and environmental signs may include exposure-related wear, moisture damage or debris that could affect valve movement.
