IC/FP

Operation

The IC/FP anti-freeze valve is installed into the lowest point within the heated system. The thermal actuator is tee’d into the NPT threaded opening with adequate internal clearance to monitor the water temperature. When the water temperature drops below the valve’s set point, typically 35°F (1.7°C), the thermal actuator modulates the valve open.

Once the makeup water temperature returns to the safe range (5 degrees above the open set point, typically 40°F [4.4°C] ), the valve then modulates closed, minimizing water waste. Due to the sensing element, the thermal actuator, always being wetted this valve is unaffected by ambient air temperature and opens only when the water is in danger of freezing.

Typical Applications

Relying on having to manually open 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 including repairing damaged equipment and piping, as well as system downtime.

The self-actuating IC/FP freeze valve eliminates the human errors associated with manual valves.

The automatic IC/FP 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. Its sensitivity to water temperature makes this valve ideal for applications where water conservation or wastewater disposal are a prime concern.
