It consists of a lead free brass body, solder union 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 degrees F (32 to 71 degrees C).
