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.
