Watts 0342691 Pressure Relief Valve 3/4" FXF 30 PSI 335M2

Watts 0342691 Pressure Relief Valve is a 3/4” female threaded valve that is essential in preventing HVAC systems from becoming over pressurized. It works on the basis of an air pressure regulator that opens the case in case the pressure rises beyond the set 30 PSI and protects the system from damage. This valve is aimed for HVAC system applications such as hydronic heating, chilled water and solar thermal systems. The advantages of this valve include improved system reliability, lower maintenance, and longer equipment life through protection from pressure-induced failure.
