AngleMix™ Angle-style three-way
thermostatic mixing valve
CALEFFI
Application
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.
Submittal Data 03705 NA — Issue Date 11/2018
Dimensions
Typical Specification
Furnish and install on the plans described herein, an AngleMix™ angle-style
three-way thermostatic mxing valve as manufactured by Caleffi. Each mixing
valve must be designed with a DZR low-lead brass body, stainless steel
springs, seals in peroxide-cured EPDM, and shutter, seats and sliding
guides in anti-scale plastic, PSU. Each valve must also be designed for
±3°F (±2°C) temperature stability with a tamper proof control knob to lock the
temperature at the set value, and mixed outlet temperature gauge. Provide
with inlet port check valves, AC models. The valve shall be ASSE 1017
approved for point of distribution installation. DZR low-lead brass body
(<0.25% Lead content) shall be certified by ICC-ES, file 1360. Meets
requirements of ANSI/NSF 372-2011. Each valve shall be Caleffi model
5205 or approved equal. (See product instructions for specific installation
information.)
