Watts 9636 Lead-free Ball Valve Union Sweat 1 in

Product Description

The WATTS 9636 is a lead-free ball valve with union sweat end connections, designed for use in potable water and hydronic piping systems. This valve features a full-port ball design that allows for quick shutoff and flow control in copper pipe installations. The union sweat configuration simplifies removal and reinstallation without cutting the line, making it a practical choice for service work and new construction alike. Licensed plumbers and pipefitters install this valve in residential and light commercial applications where lead-free compliance is required by plumbing code.

This valve is suited for residential and light commercial plumbing systems, including domestic hot and cold water lines and hydronic heating loops. The sweat end connections are compatible with standard copper tubing, and the union design allows the valve body to be serviced or replaced without disturbing adjacent piping. It is commonly installed in mechanical rooms, utility spaces, and anywhere a reliable shutoff with easy serviceability is needed.
