Lithuania Electric high vacuum butterfly valve
GID-A series electric high-vacuum butterfly valve adopts rotary electric and electronically adjustable valve drive device, which can realize valve opening, closing or intermediate through switching of external power supply (manual index switch or computer control) or external input signal. Position control, so as to achieve the purpose of turning on or cutting off the air flow in the vacuum pipeline. The valve plate of the valve adopts a clamping structure, which clamps the sealing ring of the valve plate, and has the function of fine-tuning the main seal. The applicable working medium is air and non-corrosive gas.
