Frequently Asked Questions

What is a WATTS temperature and pressure relief valve used for?

A WATTS temperature and pressure relief valve protects water heaters and boilers from overpressure and overtemperature. It automatically opens to discharge water when pressure or temperature exceeds safe limits, preventing equipment damage. This bronze ASME Section XIII valve is suitable for industrial and commercial hot-water systems.

What are the specifications of the WATTS 3/4 40XL-5-150/210 FS valve?

This WATTS valve has a bronze body with MNPTF x FNPTF connections. It is ASME Section XIII rated, with model number 3/4 40XL-5-150/210 FS. The valve is designed for temperature and pressure relief in hot-water systems. For exact pressure and temperature ratings, consult the manufacturer's datasheet.

Where to buy WATTS temperature and pressure relief valves worldwide?
