品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……
进口电动法兰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。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，现时也可关闭任一通道，使另外两个通道连通，灵活控制管路中介质的合流或分流
retz The imported electric flange three-way ball valve can switch the flow direction of the medium in the pipeline, and can also connect or close two perpendicular channels. The four seat sealed three-way ball valve not only switches the flow direction of the medium, but also enables the three channels to be interconnected. Currently, any channel can also be closed to connect the other two channels, flexibly controlling the convergence or diversion of the medium in the pipeline
功能介绍 Function introduction
进口电动法兰三通球阀用于换向分流或汇合流通，是具有二面或四面阀座的多通口球阀，任一通口可用作入口而无泄漏。三通既可制成L型通口也可制成T型通口 RETZ Three-way ball valve is used for reversing and diverting or converging flow. It is a multi-port ball valve with two or four seats. Any port can be used as an inlet without leakage. Tees can be made into L-shaped ports or T-shaped ports
L型流道的三通4面阀座球阀，采用2面阀座，受力平衡，保证闭止通道的可靠密封。主要用于流路的换向 Three-way four-side valve seat ball valve with L-shaped flow passage adopts two-side valve seat, with balanced stress, to ensure reliable sealing of the closing channel. Mainly used for commutation of flow path
T型流道的三通4面阀座，由于采用4面阀座，亚力平衡，保证闭止通道的可靠密封。主要用于分流、混流、换向以及三通道的完全开放 The three-way four-face valve seat of the T-shaped flow passage is balanced by Yali due to the four-face valve seat, which ensures the reliable sealing of the closing channel. It is mainly used for shunt, mixed flow, commutation and full opening of three channels
