Q647MF Pneumatic Ash Discharge Ball Valve (Special Ball Valve for Pulverized Coal Injection)
The Q647MF pneumatic ash discharge ball valve is a special ball valve for pulverized coal injection, used to control pulverized coal containing dust and solid powder. It is particularly suitable for blast furnace pulverized coal injection, air pipelines, and injection lance pipelines. It adopts a double-stem structure, maintaining accurate opening and closing positions over a long period; the opening and closing torque is small, flexible, and easy to use; the actuator is available in manual, pneumatic, hydraulic, and electric modes, allowing for remote control or computer program control. The unidirectional seal and inlet orifice structure are particularly suitable for gas-solid dual-mode pulverized coal injection, preventing ash accumulation and blockage; the sealing ring, sealing seat, and ball are made of special materials and processed with special techniques, resulting in wear resistance and a long service life.

Q647MF Pneumatic Ash Discharge Ball Valve (Special Ball Valve for Pulverized Coal Injection) Product Features
1. The valve seat features an automatic wear compensation device, effectively ensuring the valve’s sealing performance.
2. The sealing ring, made of special materials, is characterized by high temperature resistance, wear resistance, and long service life.
3. The valve stem is integrally forged and tempered, achieving a hardness of HB220-250. The valve stem incorporates an anti-blowout design, and can be lengthened for underground applications.
4. According to customer needs, the ash discharge ball valve can be designed with an anti-static structure. Conductive springs are installed between the ball and valve stem, and between the valve stem and valve body, preventing static electricity from igniting flammable materials and ensuring system safety.
5. Various sealing pair forms are available, including soft-seal, hard-seal, and fireproof valve seat structures, depending on different operating conditions.
6. A grease-assisted sealing structure can be installed as needed, with grease valves added to the valve seat and valve stem for temporary sealing in emergencies.
7. The pneumatic pulverized coal injection ball valve also features a compact structure, flexible opening and closing, and convenient installation and maintenance.
