Assured Automation Heat Activated Shut-Off Valve FireChek

Description: When FireChek® Senses excessive heat from a nearby fire,it immediately vents the pneumatic actuator and closes the actuator air supply line. FireChek® triggers quickly, securing pneumatically operated process line valves. Because FireChek® responds to heat, not flame, it offers dramatically improved protection compared with conventional plastic tubing burn-through. It shuts off the air supply line to prevent plant air from feeding oxygen to a fire. Features: • Rapidly responds to temperature rise, NOT flames • Vents actuator air pressure • Closes actuator air supply line • Needs no power source, self activates • Compatible with ALL pneumatic actuators • No contact with process fluids • Easy to test and reset • Reliable, intrinsic triggering • Easily retrofit, installs in minutes Performance Specifications: Actuation time: 25 seconds or less at a temperature rise rate of 30°F/min Actuation Temperature: 135, 150, or 165°F Maximum Working Control Pressure: 125 PSIG Fill and Discharge Capacity: 1 liter of air in under 1 second at 125 PSIG Cv = 0.49 Overall Dimensions: Length = 2.59" | Diameter = 1" | Weight = 0.482 lbs.
