| 1、產品特點Features |
本系列氣動球閥是作為控制含塵、含固體粉末，特別適用于高爐煤粉噴吹、空氣管路及噴**管路系統。
01、閥座帶有磨損自動補償裝置，有效確保閥門的密封性能。
02、特殊材料制成的密封圈，具耐高溫、耐磨損、適用壽命長的特點。
03、閥門結構緊湊、啟閉靈活、安裝維修方便。
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. |
