1、Features |
The Pneumatic operated ball valve series are designed for controlling the powders containing dusts or solid bodies,especially for those fields or systems as coal-powder injection in high-fumace,airflow lines, lance lines,etc. 01 .Wear-auto-compensation equipment is applied with the valve seatto effectively ensure the sealing performance of the valve. 02.The seal ring made from exotic materials features such spe-e ialtiesas high-temperature resistance, abrasion-resistance, long service-life,etc. 03.The valve bears those characteristice like compact structure, flexible on-off,and convenient method for installation and mainte-nance. |
