GQC-1.5, GQC-5 type electro-magnetic high-vacuum gas valve takes electro-magnetic force as the dynamics. When it switches in power supply, the valve shuts to separate vacuum system from atmosphere.
GQC-4A type electro-magnetic valve high-vacuum gas valve has two functions of electrified open / shut. There is an air filter in the valve. It can be used for vacuum system gas filling. The media temperature is from -25℃～ +40℃.
The applicable media for valve are air, non-corrosive gas.
GDC-J series electro-magnetic high-vacuum gas valve.
