Thermal Relief Valves

The thermal relief valve is typically installed into a pressure washer system where a maximum specific water temperature is desired.

The thermal relief valve remains sealed at low temperature levels, but as the temperature rises, the valve begins to open. The valve discharges water from the system to atmosphere, and thus maintains a desired maximum temperature. Available in 1/4", 3/8" and 3/4" NPT. Also available with a directional plastic cap.
