KROM SCHRODER电磁阀VAS系列介绍
气体电磁阀VAS与电源断开时关闭。
断开：将系统连接到电源（交流电压将被整流）。蓝色LED点亮。线圈的磁场将衔接的阀瓣向上拉动电枢。气体电磁阀VAS打开。双阀座意味着来自入口压力的力在两个阀座之间几乎均分。
关闭：将VAS与电源断开。
蓝色LED熄灭。闭合弹簧将电枢压入其初始位置。气体电磁阀在1 s内关闭。
气体电磁阀入口中的过滤器可防止污物颗粒沉积在阀座上。通过过滤器的压力损失非常低。
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.
