This 1/2'' lead free hot water control valve is designed for installation on water heating equipment to provide tempered water to point-of-use fixtures and is ideal for radiant heat applications.

It consists of a lead free brass body, Viega ProPress connections, solid wax hydraulic principle thermostat, integral filter washers and check valves, virtual shutoff upon loss of cold water supply, and a locking mechanism for the temperature setting. The maximum pressure is 150 psi (10.3 bar). The adjustable field range temperature is 90 to 160 deg F (32 to 71 deg C).
