Rembe Inc. offers the Ventex Passive Explosion Isolation Valve for isolation applications. It features a robust design that is certified to handle organic dusts, metal dusts, hybrid mixtures and gases with one-way or two-way acting systems.
The function of the passive isolation valve is very simple. During normal operation, air flows through the valve and passes around the poppet on the inside. During an explosion, the poppet is forced shut by the explosion pressure wave and locked into place. This creates a seal in the process line and effectively prevents the spread of flames and pressure. Additionally, signaling devices on all valves indicate an explosion has occurred.
