品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……(三位，L型结构)四通球阀实现正反供水切换，每动作90度 ，供水方式切换一次，工作时阀1、4口 开启，阀2、3关闭；反向供水时阀2、3开启，阀1、4 关闭，实现一台四通球阀替代四个阀门，操作方便(Three position, L-shaped structure) Four way ball valve achieves positive and negative water supply switching, with each action of 90 degrees, the water supply mode is switched once. During operation, valves 1 and 4 open, and valves 2 and 3 close; When supplying water in reverse, valves 2 and 3 open, while valves 1 and 4 close, achieving a four way ball valve to replace four valves, making operation convenient

进口四通球阀性能描述 Performance description

四通球阀任一通口均可用作入口而无泄漏，并可根据工况需要制成各种型通道，不仅可实现介质流向的切换，也可使四个通道相互连通，灵活控制管路中介质的合流或分流 RETZ Any port of the four-way ball valve can be used as the inlet without leakage, and can be made into various channels according to the working conditions. It can not only switch the flow direction of the media, but also make the four channels interconnected to flexibly control the confluence or diversion of the media in the pipeline

L型换向原理：L型结构四通换向球阀为X形垂直通道的球阀，它的特点是球体的两条通道为X形布置，四个通道口径均布于球体赤道圆周截面上，当球体沿顺时针旋转90度时，能使相近的两个通道实现两两相通  RETZ品牌 The L-shaped four-way directional ball valve is a ball valve with an X-shaped vertical channel. It is characterized by that the two channels of the sphere are arranged in an X-shaped manner, and the diameters of the four channels are uniformly distributed on the equatorial circular section of the sphere. When the sphere rotates 90 degrees clockwise, two similar channels can be connected

三位切换原理：三位结构四阀座密封四通球阀不仅可实现介质流向的切换，也可使四个通道相互连通，灵活控制管路中介质的合流或分流 

The three position four seat sealed four-way ball valve can not only switch the flow direction of the medium, but also make the four channels interconnected, so as to flexibly control the confluence or diversion of the medium in the pipeline
