Frequently Asked Questions

What is a Watts boiler pressure relief valve used for?

A Watts boiler pressure relief valve protects hot-water heating systems from overpressure. It automatically opens when pressure exceeds the set limit, preventing boiler damage or rupture. This ASME Section XIII rated valve is essential for safe operation in commercial and industrial hydronic systems.

What are the specifications of the Watts 0383310 pressure relief valve?

The Watts 0383310 is an ASME Section XIII hot-water pressure relief valve with 1 1/4 in FNPTF inlet and 1 1/2 in FNPTF outlet. It is made of iron and has an overall height of 8 3/4 in. This valve is designed for boiler overpressure protection in industrial heating systems.
