HOW IT WORKS

Reliable Protection. Simple Operation.

Rupture Pin valves use a precision buckling pin as both the pressure sensor and actuator. During normal operation, the straight pin holds the piston in a bubble-tight position. When pressure reaches the exact set point, the pin buckles and the valve moves immediately to relieve or isolate pressure.

The pin is external to the process flow, does not fragment, and can be replaced without opening the line. This helps provide dependable operation with minimal maintenance and downtime.
