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.
