本系列氣動球閥是作為控制含塵、含固體粉末,特別適用于高爐噴吹、空氣管路及噴槍管路系統(tǒng)。
1、閥座帶有磨損自動補(bǔ)償裝置,有效確保閥門的密封性能。
2、特殊材料制成的密封圈,具耐高溫、耐磨損、使用壽命長的特點。
3、閥門結(jié)構(gòu)緊湊、啟閉靈活、安裝檢修方便。
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-furnace, airflow 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 specialtes 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 mainte-nance.
