Model:  HAT/FP for freeze protection

Click here for Heat Actuated Trap product sheet

Typically, freeze protection is effected by cracking open manual bleed valves. This method is at best risky. Human error or plugging of partially cracked valves annually accounts for large amounts of freeze damage to expensive equipment. HAT/FP valves eliminate this type of problem by automating freeze protection, reducing water consumption, and eliminating damage and down time. The unique ram-type plug and seat provide reliable, tight shutoff longer than any other design available. All HAT/FP valves are factory-tested and covered by a 36 month prorated warranty.

Model Operation

A thermostatic element senses fluid temperature and if this falls below 35°F (1.7°C) the valve modulates open allowing water to flow by the sensor. The valve will remain open as long as the water flowing by the sensor is less than 40°F (4.4°C). However, when the water flowing by the sensor becomes greater than 40°F (4.4°C) the valve will close.
