The F/FG series 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 minimal waste. This intermittent operation provides substantial savings in water and sewer costs, making the F/FG series valve an ideal, economical replacement for systems with manually operated block valves that are opened seasonally. The F/FG series can also be used in most applications that involve automatic control of fluids, such as glycol, oil, light chemicals, etc.

Note: Specify temperature between 35° and 255°F in 5°F increments. Differential from full open to full closed is typically 10° to 15°F. Valve opens/closes gradually.
