Product Description
Watts 6550788 LF1170 thermostat mixing valve is a lead-free hot water temperature control valve that uses a solid wax hydraulic thermostat for thermal actuation. The 1/2 in press x press Viega ProPress connections combine hot and cold flows via a double-throttling mixing chamber to maintain an adjustable temperature range of 90 to 160 F across 0.5 to 23 GPM and a maximum working pressure of 150 psi. Includes integral filter washers, check valves, virtual shutoff, and a locking temperature setting.
- Adjustable temperature range 90 to 160 F (32 to 71 C); outlet accuracy ±7 F; minimum differential temperature 5 F.
- Press x press Viega ProPress connections, 1/2 in size; flow rate 0.5 to 23 GPM; maximum working pressure 150 psi.
- Lead-free copper silicon alloy body with integral filter washers and check valves; solid wax hydraulic thermostat; virtual shutoff on loss of cold water and locking mechanism for temperature setting.
