科恩科KNKE直动式电磁阀，Direct acting solenoidvalve，是直接靠电磁阀线圈吸力就能开启或者关闭的电磁阀，应用于零压差或自流状态的介质。
直动式电磁阀，通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。
特点：在真空、负压、零压时能正常工作
直动式电磁阀的应用范围：
科恩科KNKE直动式电磁阀是自控系统中不可缺少的执行元件，由于其体积小，开关速度快，接线简单，****，经济适用等显著特点而被普遍运用于自动化管道控制领域，发挥着巨大的作用。是各种机械设备、化工管道、等管道介质配套产品。

直动式电磁阀工作原理：
常闭：当线圈通电时，电磁阀打开。
当线圈断电时，电磁阀关闭。
常开：当线圈通电时，电磁阀关闭。
当线圈断电时，电磁阀打开。
直动式电磁阀的原理和特点是什么？
原理：常闭型直动式电磁阀通电时，电磁线圈产生电磁吸力把阀芯提起，使阀芯上密封件脱离阀座口、阀门翻开；断电时，电磁力消失，靠绷簧力把阀芯上密封件压在阀座口上、阀门关闭。（常开型与此相反） 特征：在真空、负压、零压差时能正常作业，阀口径越大，电磁头体积和功率就越大。如我公司引进HERION公司技术出产的直动电磁阀可用于1.33&TImes;10-4Mpa真空。
Konko KNKE direct acting solenoid valve is a solenoid valve thatcan be opened or closed directly by the suction of the solenoidvalve coil. It is used for media in zero differential pressure orgravity flow state.
When the direct acting solenoid valve is energized, the solenoidcoil generates electromagnetic force to lift the closing elementfrom the valve seat and open the valve; When the power is cut off,the electromagnetic force disappears, the spring presses theclosing element on the valve seat, and the valve closes.
Features: It can work normally under vacuum, negative pressureand zero pressure
Application range of direct acting solenoid valve:
Konko KNKE direct acting solenoid valve is an indispensableactuator in the automatic control system. Because of its smallsize, fast switching speed, simple wiring, high cost performance,economy and applicability, it is widely used in the field ofautomatic pipeline control and plays a huge role. It is asupporting product for various mechanical e, chemicalpipelines, and other pipeline media.
