FireChek®
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
  • Valve Made in the USA

Shape Memory Alloy Actuator
The shape memory element senses the ambient temperature and, through a phase induction change, rapidly produces the force and motion to operate FireChek®. The element is 100% reliable because the shape memory effect is intrinsic to the alloy. Shape memory alloys have performed successfully for years in military, industrial, and consumer product applications.

Operation
If FireChek® senses temperatures above the shape memory alloy's actuation temperature, the shape memory element simultaneously vents pneumatic actuator air pressure and closes upstream supply pressure. FireChek's® manual reset allows routine performance testing for safety maintenance programs. A hot-air gun will quickly actuate FireChek®. After cooling briefly, the FireChek® can easily be reset without the use of tools, for continued protection.
