KF Flange Electric Actuated High Vacuum Butterfly Valves: Overview & Technical Parameters

The KF Flange Electric Actuated High Vacuum Butterfly Valve adopts a rotary electric and electronic regulating valve drive device. It can realize the control of the valve's opening, closing or intermediate position through the switching of external power supply (using a manual indexing switch or computer control) or external input signals, thereby achieving the purpose of connecting or cutting off the gas flow in the vacuum pipeline. The applicable working medium of the valve is air and non-corrosive gases.
