明杆软密封闸阀
Rising stem resilient seated gate valve is made of good ductile iron material. The wedge has the function of exchange. Good sealing effect can be achieved by compensating for trace deformation of the elastic wedge. The valve has the advantages of light switch, reliable seal, good elastic memory and long service life. It can be widely used in tap water, sewage, construction, food, electric power, medicine, metallurgy, light textile, energy system and other fluid pipeline as a regulating and closure device.

三功能排气阀 |
三功能排气阀是安装在泵出口或供水管线中，将管道中大量的空气排出或将管道中较高层收集的少量空气排入大气中，以提高管道和泵的效率。一旦管道内部出现负压，阀门会迅速吸收外部空气，保护管道不受负压的破坏。

对夹式蝶阀 |
对夹式蝶阀是一种结构简单、体积小、重量轻的蝶阀，主要由阀体、阀板、转轴、阀座及传动装置（手柄、蜗轮箱、电动装置）等组成。只需旋转90°即可快速启闭，操作简单。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。
