Construction Features
The Air operated ball valves series are designed for controlling the powders containing dusts or solid bodies, especially for those fields or systems as coal-powder injection in high-furnace, air flow lines, lance lines, etc.
1.Wear-auto-compensation equipment is applied with the valve seat to effectively ensure the sealing performance of the valve.
2. The seal ring made from exotic materials features such specialties as high-temperature resistance, abrasion-resistance, long service-life, etc.
3.The valve bears those characteristics like compact structure, flexible on-off, and convenient method for installation and maintenance.
