产品介绍：
平板闸阀适用于Class150～900/PN1.0～16.0MPa，工作温度-29～121℃的石油、天然气、水、油品等管路上，用于截断或接通管路中的介质。
应用范围：
平板闸阀适用于天然气，石油，化工，环保，城市管道，燃气管线等输送管线，放空系统和汽储存装置上，用作启闭设备。
Z43型带导流孔单闸板式平板闸阀适用于天然气开采和净化的长输管线。
结构特点：
1、阀座采用O形密封圈密封和施加预紧力的浮动阀座结构，使平板闸阀进出口双向密封；并且该结构的启闭力矩仅为普通阀门的1/2，能达到轻松开、关阀门
2、在全开时，通道平滑为直线，流阻系数极小，无压力损失，可通毛球清扫管线
3、采用带自密封能力的填料结构，无需经常调节，开、关极为轻便，且密封性可靠，填料函处设有辅助密封油脂注入结构，密封性能绝对可靠，真正达到零泄漏；解决了通用阀门填料处最容易外漏的弊病
4、平板闸阀关闭时能自动卸掉内腔高压，保证使用安全
5、全封闭结构，防护性能好，可适应全天候要求
