Product Description

Watts Series USG-B M1 Under Sink Guardian Thermostatic Mixing Valve 3/8" (0204130)

The Watts Series USG-B Under Sink Guardian 3/8" (10mm) compression
fitting thermostatic mixing valves maintain and limit hot water to desired selectable temperature between 80°F and 120°F (27°C and 49°C) with flow rates as low as 0.5 gpm (1.9 lpm) and as high as 2.5 gpm (9.5 lpm). The mixing valve is listed under ASSE Standard 1016 for single fixture applications. The USG-B series uses a double throttling design to control both the hot and cold water supply to the mixed outlet. The superior flow characteristics of this valve provide accurate temperature control (+/- 3°F) with low pressure drop. As an added feature, the USG-B incorporates dual check valves to protect against cross-flow.

Applications:
The unit is intended for under sink installation to control the hot water temperature and prevent accidental scalding. The water temperature must be adjusted by the installer using a thermometer to measure the hot water temperature at the faucet outlet. Maximum temperature of 110°F (43°C) is recommended.

Application Note:
Delivery of water to fixtures intended for use in bathing or washing should always be controlled by valves listed to ASSE standard 1016 such as Watts series USG, MMV or L111 mixing valves. These valves provide the user with both scald protection and protection from thermal shock. The installer should always test to verify temperature setting after installation.
