产品用途

焊接蝶阀采用精密的J形弹性密封圈和三偏心多层次金属硬密封结构，被广泛用于介质温度≤425℃的治金、电力、石油化工、

以及给排水和市政建设等工业管道上，作调节流量和载断流体使用

产品特点

1、焊接蝶阀，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、蝶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焊接蝶阀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
