• Contractor friendly design - reduces installation labor and materials, the hot inlet port is in-line with mixed outlet port, eliminating a piping elbow compared to a standard mixing valve Stable mixing at low flows - consistent mixed outlet water temperature down to 0.5 gpm to meet the demands of today's low flow plumbing fixtures Posi-Stop™ unions - time saving installation and easy serviceability, Posi-Stop™ integrated O-rings provide a field proven seal connection, union tailpieces available in NPT male, press, sweat and PEX Tight hot water close-off - prevents recirculation temperature creep and droop during periods of non-use Temperature gauge included - visual verification of mixed outlet temperature with +/-1% FS accuracy gauge

The Caleffi AngleMix™ 520 series thermostatic mixing valve is used in systems producing domestic hot water and easily mounts to the top of tank style water heaters and the bottom of tankless style water heaters . The mixed temperature outlet is inline with the hot water inlet, facilitating trouble-free connection and reducing space required for installation. The AngleMix™ maintains the desired output temperature of the mixed water supplied at a constant set value compensating for both temperature and pressure fluctuations of the incoming hot and cold water. The mixing valve also features a thermal shut-off function that operates in the event of a cold water supply failure at the inlet. Also available as body only, for a wide variety of separately ordered end connections, the angle-style body design offers improved fluid dynamics for better performance and reduces installation labor and materials, eliminating a piping elbow in typical installations.
