Operation

If a FireChek® valve 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® valves' manual reset allows routine performance testing for safety maintenance programs. A hot-air gun will quickly actuate a FireChek® valve. After cooling briefly, the FireChek® valve can easily be reset without the use of tools, for continued protection.

the FireChek® valve operation.

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.
