Back-pulse valves, critical for fly ash dry filtration systems in coal chemicals, have found a new mission at ATW. Recognizing the needs of polysilicon tail gas filtration, ATW introduced this technology to the polysilicon industry.
By leveraging the valve’s rapid switching speed and intense ultrasonic vibration, ATW significantly improved cleaning efficiency and extended the service life of filter elements. Since its application in tail gas recovery and gas-solid separation units, the ATW back-pulse valve has become the industry standard.
To better serve this sector, ATW optimized the valve materials specifically for polysilicon processing, greatly enhancing reliability and stability. Today, ATW provides over 70% of the back-pulse valves used in the polysilicon industry. Our delivery and acceptance protocols have effectively become the benchmark for the entire industry.
