Flat gate valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
三通及多通球阀是流体控制系统的重要部件，广泛应用于各个工业领域。它们是球阀的变种。它们的设计允许流体在两个以上的管道之间分配或转换。三通球阀有三个接口，可以实现流体的分流、合流或切换。根据内部结构的不同，分为L型和T型。L型只能连接两根相互正交的管道，不能同时保持第三根管道的互联，只起分配作用；T型可使三根正交管相互连通，切断第三道，起到导流合流的作用。多通球阀是三通球阀的延伸，具有更多的接口和更复杂的流体控制功能。
欧菲C型球阀采用双偏心设计：C球回转中心（轴心）与C球密封面几何中心（球心）、C球回转中心与阀座密封中心的双偏心设计。阀杆在两个平面上的偏移产生C球旋转+平移的双矢量凸轮运动。阀门关闭时，C球与阀座产生凸轮楔紧的扭矩密封。扭矩密封的动力来自于手柄、齿轮、执行机构，从机械原理上确保不依赖弹簧或工艺压力而实现严密关断。
