Function
The Caleffi AngleMix™ 520 series thermostatic mixing valve is used
in systems producing domestic hot water and easily mounts to the
top of 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.
The valve has been specifically certified to ASSE 1017 and Low
Lead Plumbing Law by ICC-ES
