FLUID TEMPERATURE SENSING VALVES
Automatic Freeze Protection
The F valve is the most economical way to protect outdoor pipelines and vessels from expensive freeze damage. A thermal actuator automatically opens the valve before the temperature of the fluid drops to the freezing point. By bleeding the fluid in the system only when the danger of a freeze-up exists, the valve delivers positive freeze protection with minimum waste. This intermittent operation provides substantial savings in water and sewer costs, making the Type F valve an ideal, economical replacement for systems with manually operated block valves that are opened seasonally.
