The Buckling Pin Valve (BPV) is designed to begin activation in as little as 6 milliseconds after an internal short circuit. The piston in the valve moves upward and will buckle the pin at a pre‐determined PSI . The pin can easily be replaced while remaining installed after an event making this option the most cost effective.
The Buckling Pin Disc (BPD) is the most commonly used pressure protection device. The special design allows for very high operating pressure without the risk of fatigue over time. These discs are easy to remove, inspect and reinstall during maintenance.
