FireChek - Model FC4 Series - Heat Activated Shut-Off Valves Datasheet

When the FireChek® valve senses excessive heat from a nearby fire, it immediately vents the pneumatic actuator and closes the actuator air supply line. FireChek® valves trigger quickly, securing pneumatically operated process line valves. Because FireChek® valves respond to heat, not flame, they offer dramatically improved protection compared with conventional plastic tubing burn-through. They shut off the air supply line to prevent plant air from feeding oxygen to a fire.
