ADVANCED PRESSURE RELIEF AND ISOLATION VALVES
GET the POWER of the PIN
Precise, fully mechanical pressure protection engineered to open within milliseconds at the designated set point.
Key Advantages
☑ Bubble-tight sealing up to the set point
☑ Opens within milliseconds for rapid protection
☑ Unaffected by pulsating pressure
☑ No loose metal or plastic fragments in the flow stream
☑ Pin cannot fatigue and buckle prematurely
☑ Quick reset without opening the line to atmosphere
☑ Visual indication with optional remote monitoring
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.
