電磁閥（Solenoid valve）是用電磁控制的工業(yè)設(shè)備，主要特點(diǎn)安全、方便、型號多、用途廣，
是用來控制流體的自動化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動。用在工業(yè)控制系統(tǒng)中
調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制，
而控制的精度和靈活性都能夠保證。電磁閥有很多種，不同的電磁閥在控制系統(tǒng)的不同位置
發(fā)揮作用，最常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。
Solenoid valve is an industrial equipment controlled by electromagnetism. It is safe,
convenient, multi-type and widely used,is used to control the basic components of fluid
automation, belongs to the actuator, not limited to hydraulic, pneumatic. Used in industrial control systems
Adjust the direction of the medium, flow, speed and other beters. Solenoid valves can be used with
different circuits to achieve the desired control,the control accuracy and flexibility can be guaranteed.
There are many kinds of solenoid valve, different solenoid valve in the control system in different bs
