Construction Features

The Air operated ball valve series are designed for controllingthe powders containing dusts or solid bodies, especially for thosefields or systems as coal-powder injection in high-furnace, airflowlines, lance lines, etc.
1.Wear-auto-compensation equipment is applied with the valveseat to effectively ensure the sealing performance of the valve.
2.The seal ring made from exotic materials features such spe-c ialties as high-temperature resistance,abrasion-resistance, longservice-life, etc.
3.The valve bears those characteristics like compact structure,flexible on-off, and convenient method for installation and mainte-nance.
