burkert5281 B 20.0 G3/4 0.2-16bar德国BURKERT电磁阀全部系列 分布直动式电磁阀 原理： 它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动

burkert5281 B 20.0 G3/4 0.2-16barBURKERT产品大致分为六大类：“通用电磁阀系统”“过程控制阀系统”“气动控制阀系统”“液体分析阀系统”“传感器/变送器”和 “控制器”，很多产品达到卫生级标准。   电磁阀是用来控制流体的方向的自动化基础元件，属于执行器；通常用于机械控制和工业阀门上面，对介质方向进行控制，从而达到对阀门开关的控制。电磁阀从原理上分为三大类直动式电磁阀 原理：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，但通径一般不超过25mm。BURKERT products roughly divided into six categories: "general solenoid valve system" "process control valve system" "pneumatic control valve system", "analysis of liquid valve system" "sensor/transmitter" and the "controller", a lot of products reach the standard level of health. The solenoid valve is an automatic basic component used to control the direction of the fluid. Normally used for mechanical control and industrial valves, control of medium direction to achieve the control of valve switch. The electromagnetic valve is divided into three main types of direct acting solenoid valve principle: when energized, the electromagnetic coil generates electromagnetic force to lift off the closing piece from the seat and the valve opens; When the power is off, the electromagnetic force disappears and the spring closes the closing piece on the seat and the valve closes. Features: it can work normally when vacuum, negative pressure and zero pressure, but not more than 25mm.
