产品特点 　　K23D系列微型电磁阀是气压传动系统中的基本元件，常作为大流量换向阀的先导控制，故亦称电磁先导阀，同时也可直接控制耗气量小的执行机构。 　　K23D series micro solenoid valvesare the basic elements in pneumatic transmission system often used us the pilot control of big flow rate directional valves and that is why they are called solenoid pilot. They can also be used to control directly the execution mechanism with small air flow rate.
