Explosion isolation valves provide an additional layer of protection. They are installed in the inlet ducting to create a mechanical barrier that keeps the explosion flame and pressure from traveling through ducts into the process area. Normal airflow keeps the flap plate open. But if an explosion occurs, the pressure wave forces the flap closed, containing the flames and smoke.
