The HAT/FP is a self-acting freeze protection valve designed to prevent piping and equipment damage by discharging water when temperature drops to 35°F (1.7°C) and closing when it rises above 40°F (4.4°C). It features a stainless steel body, fittings, and plug, with a Thermoloid® thermal actuator and ram-type plug for reliable shutoff. Available in 1/2" and 3/4" NPT sizes, it operates without external power and includes two wrench flats for installation. The valve is rated for a maximum operating pressure of 300 PSIG (20.7 BAR) for 1/2" port and 150 PSIG (10.3 BAR) for 3/4" port in reverse flow. Some variants are NSF/ANSI/CAN 61 & 372 certified. The valve can be configured for ambient or fluid sensing, with optional integrated strainer.
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 loss including repairing damaged equipment, piping, as well as system downtime.
The self-actuating HAT/FP valve eliminates the human errors associated with manual valves. This automatic valve is ideal for the protection of piping, safety showers, solar collectors & piping, condensate systems, fire lines, spray nozzles, or as backup protection on traced systems.
The HAT/FP-35 will initiate flow when the thermostatic actuator senses 35°F (1.6°C) and will remain open as long as the discharge water temperature is below 40°F (4.4°C).
In standard flow, the actuator will sense ambient temperature to initiate flow and then respond to water temperature; in reverse flow, the actuator will sense water temperature.
