(T型,L型结构)进口内螺纹三通球阀性能描述 Performance description
两阀座密封三通球阀能实现对管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭 Two seat sealed three-way ball valve can switch the flow direction of medium in the pipeline. It can also connect or close two mutually perpendicular channels
四阀座密封三通球阀不仅可实现介质流向的切换,也可使三个通道相互连通,同时可关闭任意一个通道,使另外两个通道连通,灵活控制管路是介质的合流或分流 retz品牌 The four seat sealed three-way ball valve can not only switch the flow direction of the medium, but also make the three channels interconnected. At the same time, it can close any channel to make the other two channels connected. The flexible control pipeline is the confluence or diversion of the medium
