The Interceptor-QV is a new patented explosion isolation device built with the principles of flameless venting. A stainless steel mesh cartridge in the center of the device works to stop a deflagration. If a deflagration propagates through the clean return line it will make contact with the mesh cartridge. The cartridge removes energy from the flame front of the deflagration as it passes through the torturous path of the mesh, forcing the flame to transfer its energy to the high surface area of the mesh, thereby quenching the deflagration and not allowing any flame to pass beyond the Interceptor-QV.

The Interceptor®-VE® is a NFPA 69 compliant isolation pinch valve. The Interceptor®-VE® valve is normally open. Upon receiving a signal from either a pressure responder or an optical sensor the Interceptor®-VE® controller is designed to immediately signal the Interceptor®-VE® valve. The Interceptor®-VE® valve will close in milliseconds to prevent the passage of hot particles, glowing embers, flame, or pressure from continuing to flow through the pipe. The medium of actuation is plant compressed air stored in a tank on the valve to ensure the fastest response possible under any plant conditions.

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.
