As a core industrial device for material storage and conveying, the Ash Discharge Valve discharges dust, particles and other solids quantitatively and continuously under sealed conditions. It isolates internal and external air pressure to prevent leakage and secondary dust emission, and maintains stable pressure in dust removal and pneumatic conveying systems.

The Sealed Ash Discharge Valve is a core component for pneumatic conveying systems, developed by Botou Xintian Environmental Protection Equipment Co., Ltd.—a leader in industrial environmental solutions with ISO9001 certification. This Pneumatic Conveying Ash Valve features ultra-high sealing performance, solving the common problems of ash leakage and air leakage in traditional valves. It is engineered for continuous and stable operation in harsh industrial environments, efficiently discharging ash, powder, and granular materials while maintaining system pressure balance. As a trusted Industrial Air-Tight Ash Discharge Valve, it serves B-end customers in power plants, cement factories, and metallurgical industries, delivering reliable performance and reducing operational costs.
The valve adopts a double-sealing design (metal-to-metal primary seal + wear-resistant rubber secondary seal) to achieve air tightness ≤0.02 MPa. The valve plate is precision-machined via robot welding technology, ensuring tight fit with the valve body and preventing ash leakage even under high-pressure conditions. This design reduces energy loss by 15% compared to conventional valves.
The internal flow channel is optimized with a streamlined structure, reducing material adhesion and accumulation. The valve’s impeller is made of wear-resistant alloy steel (subjected to nitriding oxidation treatment), enhancing its wear resistance and preventing jamming caused by hard particles. It supports continuous operation for 24 hours without manual intervention.
The valve body is coated with anti-corrosion paint, while key components are treated with nitriding oxidation to resist corrosion from acidic and alkaline ash. This ensures stable performance in harsh environments (temperature range: -20℃ to 200℃), extending the service life to 5-8 years.
Adopting a modular design, the High-Seal Pneumatic Conveying Discharge Equipment can be quickly installed and connected to existing pneumatic conveying systems. The detachable valve cover and replaceable seal rings simplify maintenance, reducing downtime and labor costs for customers.
