Product description:

Slag valve, also known as lock bucket valve, commonly it is used in coal-water slurry of coal gasification slag tapping, multiplex slurry and pressurized gasfication system of dry coal powder flow bed, involved in the slagging process control of gasfication furnace, the applicable medium is the black water with ash, with a certain degree of chemical corrosion and strong mechanical corrosion, the valve is frequently to be opened and closed.the applicable actuator is pneumatic, electro-hydraulic; the connection way with the pipe is generally flange. The seal surface of slag valve is metal to metal structure, the packing is flexible graphite, the gasket is stainless steel with flexible graphite. Therefore, the valve ensures a reliable seal even in the case of fire.
