Vacuum valve -Butterly valve
GID-A Series Electric high-vacuum Butterfly Valve
GID-A Series Electric High-vacuum Butterfly Valve adopts the rotary electric, electronic regulation type valve drive device. It can fulfill the valve open,close or intermediate position control through externally-connected power source conversion (by manual indexing switch or computer control) or outer input signal. It is applicable for connecting or cutting off the airflow in vacuum tubes.
This series valve plate adopts the clamping structure. It tightly grips the valve plate seal ring. Apart from the capability of this valve being used in vacuum conditions, it can also bear certain pressure.
The applicable active medium of this valve are air, non-corrosive gas.
