Description
The Watts 0276349 1-1/2” Pressure Relief Valve is an essential safety item that can prevent pressure build up in HVAC systems. This 174A series valve has a 1-1/2” FEM NPT connection and a body made of bronze and it operates at a pressure relief setting of 35 PSI. If pressure at the system level rises beyond this level, the valve is triggered to open and communicate reduced pressure to prevent the deterioration of apparatuses while functioning as planned. It is widely used in different HVAC system cases such as chillers, boilers, and pumps to protect the equipment from dangers that arise due to high pressure.
