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……进口电动隔膜阀不需要单独的阀杆填料密封结构，隔膜在切断介质的同时起到了阀杆的密封作用，其二是柔韧性很强的隔膜关闭可靠，甚至对污液都能做到良好的切断Retz Imported electric diaphragm valves do not require a separate valve stem packing sealing structure. The diaphragm serves as a seal for the valve stem while cutting off the medium. Secondly, the highly flexible diaphragm ensures reliable closure, and can even effectively cut off dirty liquids

进口电动隔膜阀主要性能 Main performance
电动隔膜阀由电动执行机构和隔膜阀组成,使阀杆作轴向运动时，使阀芯上下运动，同时拉动膜片上下运动使其关闭和打开,当电源发生故障而中断时，且阀门急需启闭的紧急状况下，首先应将手—电动切换手柄转换至刻有手动标记的位置上，然后可通过旋转手轮使闪门启闭。当顺时针方向旋转时，阀门即可关闭；反之则开启 RETZ The electric diaphragm valve is composed of an electric actuator and a diaphragm valve. When the valve stem moves axially, it causes the valve core to move up and down, while pulling the diaphragm up and down to close and open. When the power supply is interrupted and the valve urgently needs to be opened or closed in an emergency situation, the manual electric switching handle should be first switched to the position marked with a manual mark, and then the flash door can be opened or closed by rotating the handwheel. When rotating clockwise, the valve can be closed; _disibledevent="font-size:7.5pt;font-family:"Times New Roman","serif"">The products cover: imported pneumatic diaphragm valves, electric diaphragm valves, rubber lined diaphragm valves, fluorine lined diaphragm valves, straight through diaphragm valves, angle diaphragm valves, American standard diaphragm valves, German standard diaphragm valves, Japanese standard diaphragm valves, British standard diaphragm valves, glass lined diaphragm valves, vacuum diaphragm valves, stainless steel diaphragm valves, sanitary grade diaphragm valves, unlined diaphragm valves, PVC diaphragm valves, PFA high cleaning fluorine plastic diaphragm valves, high-purity diaphragm valves
