Replacement Gas Valve

The Watts TB1156F is a 1/2-inch bronze feed water pressure regulator engineered for commercial and residential hydronic heating systems. This high-capacity regulator is designed to fill boilers and piping, maintain system pressure, and provide automatic make-up water to compensate for system leaks. The unit features a tight-seating check valve that effectively prevents backflow, ensuring system integrity and protecting against water loss. A manual purge lever allows operators to vent air from the system when needed for optimal performance. The simplified servicing design enables quick maintenance and repairs with minimal downtime. An integral stainless steel strainer protects the valve disc from fouling caused by debris or sediment in the water supply, extending the regulator's operational life. The inlet connection features a 1/2-inch female NPT union threaded design for straightforward installation in standard piping configurations. Built with a bronze body for corrosion resistance and durability in wet environments, this regulator combines reliable performance with practical design features ideal for heating contractors and facility maintenance professionals. The high-capacity design ensures consistent pressure regulation even in demanding applications, making it suitable for both new installations and replacements.
