Explosion Isolation Valve

The Explosion Isolation Valve is designed to protect your facilities and employees by preventing an explosive force from within a baghouse or filtration system from moving past the valve. Without an isolation valve, if a fire or explosion takes place, burning fuel and explosive force rapidly expands and can enter the building through the suction side duct system, causing severe injury and damage to property.
