电动硬密封球阀Q947H用途：
电动球阀是一种转角为90°的旋转类球阀，密封性能优良，流通能力大，流阻系数小，结构简单、维修方便、使用寿命长，阀体通道和连接管径相等并成一直径，介质几乎可以毫无损失的流过。配用DKJ-Ⅱ、Ⅲ执行器引配日本工装、西德欧姆龙等高性能执行机构。产品通常用于密封要求严格的场合，除控制气体、液体、蒸汽介质外，还适宜控制污水和含有纤维性杂质的介质，广泛用于石油、化工、冶金、轻工、造纸、电站、制冷等工作领域。
电动硬密封球阀Q947H是一种重要的阀类，在石油化工、长输管线等领域有广泛应用。球阀的关闭件是一个带孔的球体（或部分球），球体随阀杆转动，实现阀门的开启或关闭。
电动硬密封球阀Q947H旋转90°即可全关全开，与相同规格的闸阀、截止阀比较、球阀体积小、重量轻，便于管道安装。
