Shanghai Metal Corporation is a leading explosion proof valve manufacturer and supplier.
When deflagration and explosion occur on the outlet side of the explosion-proof valve, due to an increase in back pressure, the airflow flows in the opposite direction, causing the back pressure valve disc to close. The throttle blade is tightly closed on the inclined end face of the inlet side, preventing the explosion from spreading to upstream pipelines and equipment, playing a role in isolation.
