solenoid directional control valve

solenoid directional control valveIt uses an electromagnet to push the valve core to control the direction of liquid flow. adoptsolenoid directional control valveIt can make the operation lightweight and easy to automate, so it has a wide range of applications.
solenoid directional control valveJust using an electromagnet to manipulate the movement of the spool valve, and the structure and type of the spool valve can be various, so the electromagnetic spool valve can be in various types such as two position two-way, two position three-way, two position four-way, three position four-way, and three position five way. Generally, a two position valve requires one electromagnet, while a three position valve requires two electromagnets. manipulatesolenoid valveThe electromagnets used are divided into two types: AC and DC,Communication electromagnetThe voltage is generally 220 volts. Its characteristics are high starting force, short switching time, and low cost. However, when the valve core is stuck or the suction force is insufficient, causing the iron core to fail to suck up, the electromagnet is prone to burning out due to excessive current, resulting in poor reliability, impact during operation, and lower lifespan.DC electromagnetThe voltage is generally 24 volts. Its advantages are reliable operation, no burning caused by valve core jamming, long service life, small size, but smaller starting force than AC electromagnets, and the need for rectification equipment when there is no DC power supply. In order to improve the reliability and lifespan of work, wet electromagnets have been increasingly widely used both domestically and internationally in recent years. This type of electromagnet does not require sealing between the electromagnet and the slide valve push rod, eliminating the friction at the O-ring seal. Its electromagnetic coil is directly sealed with engineering plastic without a separate metal shell, which ensures insulation and facilitates heat dissipation, resulting in reliable operation, low impact, and long lifespan.
