进口钢制德标球阀 DIN标准不锈钢球阀 美国RETZ瑞茨

　　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……din德标钢制球阀在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀 whendin german standard steel ball valves are fully open or fully closed, thesealing surfaces of the ball and valve seat are isolated from the medium. whenthe medium passes through, it will not cause erosion of the valve sealingsurface

　　进口钢制德标球阀性能描述performance deion

　　(din)德标钢制球阀阀芯从结构上看，密封时球体阀座嵌在阀体侧阀座上，开闭操作通过将手柄旋转 90 度，可使流体停止流动 retz (din)german standard steel ball valve core from the structure, when sealing, theball valve seat is embedded in the valve seat at the side of the valve body.the opening and closing operation can stop the flow of fluid by rotating thehandle 90 degrees
