this component triggers an open circuit at 160°F and automatically resets (closes) once the temperature drops to 140°F

Rugged Construction: Built to withstand the high-temperature environment of standard flue gas venting

Common symptoms include a high-pitched whistling noise

Always verify the specific frame size of your temperature restraining device before field installation

automatic reseating temperature and pressure relief valve engineered for critical protection in commercial water heating systems

Belimo Z2050Q-F Valve Body 322057-301 this component triggers an openThe Belimo Z2050Q F is a 1 2" 2 way zone valve body engineered for high performance modulation in commercial hydronic systems. Featuring a Cv rating of 1. 4 and a forged brass construction, this valve is designed to handle the rigorous demands of fan coil units, VAV reheat coils, and radiant panels. Its equal percentage flow characteristic ensures linear heat output, preventing the "hunting" common in less precise valve bodies. With a 360 psi body
