Interceptor - Model SG -Explosion Isolation Slide Gate Valve
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 state releasing the compressed air.
The Interceptor®-SG® is a completely air operated slide gate valve, compliant with NFPA 69 standards. The Interceptor®-SG® slide gate valve is a normally open device with pneumatic air cylinders containing compressed air to lock the valve shut once a signal from a pressure detector is received, indicating the start of a deflagration.
The air operated Interceptor®-SG® slide gate valve can be quickly rearmed at the controls after activation without any rebuild or ignitor replacement. The valve’s stainless-steel bore makes it ideal for food-grade applications, as well as almost any system, including pneumatic conveying systems, dust collection systems, cyclones, mills, storage vessels, and metal dust applications.
