費斯托FESTO電磁閥566496 VUVG-L14-T32C-AT-G18-1P3

直動式電磁閥原理:通電時,電磁線圈產(chǎn)生電磁力把關閉件從閥座上提起,閥門打開;斷電時,電磁力消

失,彈簧把關閉件壓在閥座上,閥門關閉。特點:在真空、負壓、零壓時能正常工作,但通徑-般不超過2

5mm。分步直動式電磁閥原理:它是一種直動和先導式相結合的原理,當入口與出口沒有壓差時,通電

后,電磁力直接把先導小閥和主閥關閉件依次向上提起,閥門打開。當入口與出口達到啟動壓差時,通電

后,電磁力先導小閥,主閥下腔壓力上升，上腔壓力下降,從而利用壓差把主閥向上推開;斷電時,先導

閥利用彈簧力或介質壓力推動關閉件,向下移動,使閥門關閉。特點:在零壓差或真空、高壓時亦能可*動

作,但功率較大,要求必須水平安裝。先導式電磁閥原理:通電時,電磁力把先導孔打開，上腔室壓力迅

速下降，在關閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;斷電時,彈簧力

把先導孔關閉,入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向

下移動，關閉閥門。特點:流體壓力范圍上限較高，可任意安裝(需定制)但必須滿足流體壓差條件。

Festo FESTO solenoid valve 566496 VUVG-L14-T32C-AT-G18-1P3

Principle of direct acting solenoid valve: When energized, the electromagnetic coil generates electromagnetic force to lift the closing part from the valve seat, and the valve opens; When power is cut off, electromagnetic force is dissipated

The spring presses the closing element against the valve seat, causing the valve to close. Characteristics: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 2

5mm。 Principle of step-by-step direct acting solenoid valve: It is a combination of direct acting and pilot operated principle, which is energized when there is no pressure difference between the inlet and outlet

Afterwards, the electromagnetic force directly lifts the pilot small valve and the main valve closure piece upwards, and the valve opens. When the starting pressure difference between the inlet and outlet is reached, power on

Afterwards, the electromagnetic force leads the small valve, causing the pressure in the lower chamber of the main valve to increase and the pressure in the upper chamber to decrease, thereby using the pressure difference to push the main valve upwards; During power outage, the pilot

The valve uses spring force or medium pressure to push the closing element downwards, causing the valve to close. Features: It can also be operated at zero pressure difference, vacuum, and high pressure

However, due to its high power, it is required to be installed horizontally. Principle of pilot operated solenoid valve: When energized, electromagnetic force opens the pilot hole and the upper chamber pressure is rapid
