The Interceptor®-SG® explosion isolation valve is designed to prevent explosion propagation from one vessel to another through interconnected piping. The explosion isolation slide gate is a compliant solution for both NFPA 69 and FM 7-76.

The isolation valve is a normally open device, however, upon receiving a signal from a pressure detector, the Interceptor®-SG® explosion isolation valve is designed to rapidly close. The medium for actuation is plant-compressed air stored in a tank on the valve to ensure the fastest response possible under any plant conditions. The valve closure principle is a slide gate that closes when a high-speed solenoid valve changes the state releasing the compressed air.
