As the core unloading equipment for powder pneumatic conveying systems, the rotary discharge valve features reliable air-locking and quantitative discharging performance. It is widely used for material conveying working conditions in industrial dust removal, powder processing, building materials, chemical, grain and other industries.

The star discharge valve boasts prominent core advantages. Its valve body adopts a cast structure with PN10 flange pressure rating, suitable for butt joint with DN240 pipelines and delivering stable pressure resistance. The rotor blades are precision-machined with tightly controlled clearances between blades and housing, achieving excellent air-locking performance to effectively prevent air channeling and leakage and stabilize the pressure of the pneumatic conveying system. The drive end is equipped with a cycloidal pinwheel reduction motor and chain drive structure, providing sufficient operating torque and smooth transmission to support continuous 24-hour non-stop operation. The whole unit allows variable frequency speed regulation to adjust discharge flow on demand and realize quantitative and uniform feeding. The inner cavity of the valve is coated with anti-corrosion paint for wear and rust resistance, applicable to dry powder and granular materials. Its detachable structure facilitates inspection and cleaning of internal material deposits, greatly cutting subsequent operation and maintenance costs.

In pneumatic conveying circuits, conventional unloading devices tend to suffer from air leakage and backflow, which reduce conveying efficiency. This product realizes air locking through precise rotor clearances and maintains system pressure under both negative-pressure dust collection and positive-pressure feeding conditions. Featuring strong versatility, the equipment supports customized options such as high-temperature resistance, wear resistance and anti-corrosion tailored to material properties to adapt to various powder and granular media with outstanding cost performance.

The star discharge valve serves a wide range of application scenarios: ash discharge from hoppers of baghouse dust collectors, as standard air-locking discharge equipment for dust removal systems; quantitative discharging of building material powders including cement, lime powder and mineral powder; closed conveying and feeding of chemical powders and plastic pellets; discharging of grains, bran and particles in grain processing industry; feeding of fuel powders such as biomass and coal powder. The equipment can operate stably for a long time under negative pressure and slight positive pressure environments and meet industry specifications for environmental dust removal and closed conveying.
