Coal Feeder Discharge Valve

The coal feeder discharge valve is a dedicated on-off valve installed at the discharge outlet of coal feeders. It is widely used in thermal power plants, coal yards, cement plants and other industries, serving to cut off, connect and control the discharge of lump coal, pulverized coal and other bulk materials. It works stably under continuous material impact and dusty working conditions, ensuring the safe and orderly operation of coal feeding systems.

Main Features

Excellent Wear Resistance

The valve body and sealing parts adopt wear-resistant materials and surface hardening treatment, effectively resisting abrasion from coal particles and prolonging service life. The streamlined internal structure avoids material accumulation and blockage.

Flexible Operation & Multiple Drive Options

Available with electric, pneumatic and manual driving modes. It supports remote automatic control and on-site manual operation, featuring quick opening and closing, which adapts to frequent start-stop working requirements of coal feeders.

Good Sealing Performance

Special dust-proof sealing structure prevents coal dust leakage, keeping the on-site environment clean and reducing material waste. It can adapt to positive and negative pressure working conditions.

Simple Structure & Easy Maintenance

Compact overall design with fewer vulnerable parts. Disassembly, inspection and part replacement can be completed quickly, lowering daily maintenance costs.

Application

Primarily matched with various coal feeders, applied to coal conveying, bunker discharging and material feeding systems in power, metallurgy, chemical and building material industries.
