  • F/FG Series Automatic Freeze Protection and Fluid Temperature Valves

    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.

  • FP/FPR Series Emergency Showers Freeze and Scald Protection Valves

    The FP/FPR series valves feature a space-saving, in-line design and high/low temperature sensitivity to provide positive freeze/scald protection for emergency safety showers and eyewash stations.Freeze ProtectionThe low temperature actuated FP series provides the same basic freeze protection as the F/FG series valves, but with a straight-through flow area larger than the pipe diameter for unrestricted flow.Scald ProtectionThe reverse acting FPR series valve is actuated by temperatures in excess of 100°F due to overheating, direct sunlight or other heat source. Discharge stops when temperature drops below 90°F. Full flow to shower head is also assured.

    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.

  • FR/FGR Series Cooling Systems Automatic Control Valves

    The reverse-acting FR/FGR series valve is an inexpensive way to maintain optimum discharge temperatures for more efficient and economical use of your cooling media. Because of its reverse action design, the valve closes when fluid temperature drops below a preset temperature — effectively eliminating the inefficient discharge of low temperature cooling fluid.Controlled leakage* can be provided through the valve for constant, true temperature monitoring. The FR/FGR series valve is an economical way to maintain optimum operating temperature of equipment for maximum efficiency.

    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.
