Description

Temperature Actuated Mixing Valves for Hot Water Distribution Systems (herein referred to as "device") shall consist of a hot water inlet connection, a cold water inlet connection, a mixed water outlet connection, a thermal element or thermostatic sensor and a means for adjusting the mixed water outlet temperature. These devices can be either mechanically actuated or electronically controlled device.

Connections

Dimensions of pipe threads, flanges and other connections shall conform to appropriate industry standards.

Maximum Working Pressure

The maximum static pressure of the device shall have a minimum value of 125.0 psi (861.9 kPa).

Temperature Range

a) Supply Water Temperature Range

The hot water supply temperature range shall be 125.0 °F ‐ 180.0 °F (51.7 °C ‐ 82.2 °C) and the cold water supply temperature range shall be 35.0 °F ‐ 80.0 °F (1.7 °C ‐ 26.7 °C).

b) Outlet Water Temperature Range

The device shall be capable of supplying the hot water distribution system with a minimum adjustable range of 105.0 °F ‐ 120.0 °F (40.6 °C ‐ 48.9 °C), provided the hot water supply temperature is at least 20.0 °F (11.0 °C) greater than the outlet water temperature setting.

Compliance with Safety Standards

Electrical controls shall comply and be categorized as operating controls with Class A control functions per UL 60730‐1 and UL 60730‐2‐9 or comply with the applicable requirements of UL 429.
