、本阀采用三偏心密封结构，阀座与蝶板几乎无磨损，具有越观越紧的密封功能。
2、密封圈选用不锈钢制作，具有金属硬密封和弹性密封的双重优点，无论在低温和高温的情况下，均具有优良的密封性能,具有耐腐蚀,使用寿命长等特点。
3、碟板密封面采用堆焊钴基硬质合金，密封面耐磨损，使用寿命长．
4、大规格蝶板采用绗架结构，强度高，过流面积大，流阻小。
5、本阀具有双向密封功能，安装时不受介质流向的限制，也不受空间位置的影响，可在任何方向安装。
6、驱动装置可以多工位（旋转90°或180°）安装，便于用户使用。
五、电动法兰式硬密封蝶阀D943H-10/16/25/电动硬密封蝶阀主要外形连接尺寸(单位:mm)：
