KROM SCHRODER電磁閥VAS系列介紹
氣體電磁閥VAS與電源斷開時關閉。
斷開：將系統連接到電源（交流電壓將被整流）。藍色LED點亮。線圈的磁場將銜接的閥瓣向上拉動電樞。氣體電磁閥VAS打開。雙閥座意味著來自入口壓力的力在兩個閥座之間幾乎均分。
關閉：將VAS與電源斷開。
藍色LED熄滅。閉合彈簧將電樞壓入其初始位置。氣體電磁閥在1 s內關閉。
氣體電磁閥入口中的過濾器可防止污物顆粒沉積在閥座上。通過過濾器的壓力損失非常低。
The gas solenoid valve VAS is closed when it is disconnected from the power supply.
Opening: Connect the system to the electrical power supply (alternating voltage will be rectified). The blue LED lights up. The coil’s magnetic field pulls the armature with the attached valve disc upwards. The gas solenoid valve VAS opens. The double valve seat means that the forces from the inlet pressure are divided almost equally between the two valve seats.
Closing: Disconnect the VAS from the electrical power supply.
The blue LED goes out. The armature is pressed into its initial position by the closing spring. The gas solenoid valve closes within 1 s.
The strainer in the inlet of the gas solenoid valve prevents deposits of dirt particles on the valve seats. The pressure loss through the strainer is very low.
