Reverse Blower Integral Double Gate Valve

Reverse blower integral double gate valve is a kind of valve widely used in flue gas purification system, mainly used to control the flow of flue gas and reverse blower. The valve adopts double structure design, that is, two RAMS are set in a valve body, which can independently control the flow of flue gas and reverse blower, with higher control accuracy. The gate of the valve adopts special anti-clogging design, which can effectively prevent the accumulation of particulate matter and dust in the flue gas between the gate and ensure the normal operation of the valve.
