Williams Comfort Products 8V38R Pressure Relief Valve

Product Description

The WILLIAMS COMFORT PRODUCTS 8V38R is a pressure relief valve designed to protect hydronic and heating system components from unsafe pressure buildup. When system pressure exceeds the rated threshold, the valve opens to release excess pressure and prevent equipment damage or failure. This type of safety valve is a standard component in boiler and water heater installations, and is typically installed or replaced by licensed plumbers or HVAC technicians performing system service or commissioning.

Pressure relief valves like the 8V38R are used in residential and light commercial heating systems, including hot water boilers and hydronic heating equipment. The valve provides a critical safety function by venting pressure before it can compromise the pressure vessel or connected piping. It is sold as an individual unit, making it suitable for single-point replacement during routine maintenance or system repair.

Installation Notes

Installation and replacement of pressure relief valves should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and ASME requirements. Shut off the water supply and depressurize the system before removing the existing valve. Ensure the replacement valve is installed with the discharge outlet directed toward an appropriate drain or relief pipe. Never cap or plug the discharge outlet of a pressure relief valve.
