Thermostatic Mixing Valve for Hot Water Systems

This CASH ACME valve blends hot and cold water to a controlled temperature between 85 and 130 degrees F. It fits 1/2 inch push-fit inlets and outlets on residential or light-commercial supply lines. The brass body meets ASSE 1017, 1069, 1070 and NSF 61 standards for potable water safety. It is intended for installers who need a certified mixing point at the fixture or manifold.

Temperature Range and Pressure Rating

The adjustable outlet range spans 85 to 130 degrees F, which determines whether the valve can deliver the required safe temperature for showers, lavatories or tub fillers. Maximum working pressure is 200 psi, so the part suits typical municipal or well-pump supplies without additional pressure reduction. If the design calls for a higher outlet temperature or a pressure above 200 psi, this valve will not meet the specification.

Thermal Stability and System Load

The thermostatic element reacts to inlet temperature changes to hold the mixed outlet steady, limiting scald risk during normal demand fluctuations. Brass construction resists corrosion and mineral buildup, preserving response time over the service life. No external power or control signal is needed; the valve operates purely on supply pressure and thermal expansion. Installers should verify that the hot source can maintain flow within the 85 to 130 degree F window under peak draw.
