FireChek® valve

The new Firechek FC-4 Series valve from Assured Automation is a FM approved heat activated pneumatic shut-off valve. When the shape memory alloy of the 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. It shuts off the air supply line to prevent plant air from feeding oxygen to a fire. The element is 100% reliable because the shape memory effect is intrinsic to the alloy. The element senses the ambient temperature and through a phase induction change, rapidly produces the force and motion to operate FireChek. Firechek’s manual reset allows routine performance testing for safety maintenance programs.
