電動硬密封球閥Q947H用途：
電動球閥是一種轉角為90°的旋轉類球閥，密封性能優良，流通能力大，流阻系數小，結構簡單、維修方便、使用壽命長，閥體通道和連接管徑相等并成一直徑，介質幾乎可以毫無損失的流過。配用DKJ-Ⅱ、Ⅲ執行器引配日本工裝、西德歐姆龍等高性能執行機構。產品通常用于密封要求嚴格的場合，除控制氣體、液體、蒸汽介質外，還適宜控制污水和含有纖維性雜質的介質，廣泛用于石油、化工、冶金、輕工、造紙、電站、制冷等工作領域。
電動硬密封球閥Q947H是一種重要的閥類，在石油化工、長輸管線等領域有廣泛應用。球閥的關閉件是一個帶孔的球體（或部分球），球體隨閥桿轉動，實現閥門的開啟或關閉。
電動硬密封球閥Q947H旋轉90°即可全關全開，與相同規格的閘閥、截止閥比較、球閥體積小、重量輕，便于管道安裝。
