The freeze valve will initiate flow when the thermostatic actuator senses 35°F (1.7°C) and will remain open as long as the discharge water temperature is below 40°F (4.4°C). The actuator will sense ambient temperature to initiate flow and then respond to water temperature. Relying on manually opening valves for freeze protection allows for human error or plugging of partially cracked valves. This annually accounts for large amounts of freeze damage resulting in huge monetary losses associated with repairing damaged equipment, piping, as well as system downtime.The self-actuating freeze valve eliminates the human errors associated with manual valves. The automatic freeze valve is ideal for the protection of piping, valves, fittings, pumps, safety showers, condensate systems, fire lines, spray nozzles, or as backup protection on traced systems.
