1、单向水阀降低用户的成本。同时提高了阀座使用寿命（是普通中线阀的3-4倍）。4、阀座法兰密封面采用大宽边、大圆弧的结构，使阀门完全可以适应套合式或焊接式法兰联接要求，适合与任何标准法兰联接。5、阀杆轴向定位装置，采用两垫片加一对开环和弹簧卡圈结构方式。这样亦可有效防止阀杆无意地被拆卸，同时又可承载一定的轴向力，防止阀杆重量传递给蝶板。6、阀杆密封圈起双向密封作用，即防止外来物质侵入，同时阻止介质外流。7、轴套既起支撑阀杆的作用，同时又可降低启闭扭矩。目前有两种轴套可供用户选择，即：润滑青铜、聚四氟乙烯。8、由于阀体本身替代普通阀座的靠背，增加了阀门整体强度，使之能够达到普通中线蝶阀无法实现的20
