GDC-J series electromagnetic high vacuum baffle valveDetailed product description：

The GDC-J series electromagnetic high vacuum baffle valve is a valve that relies on electromagnetic force and spring reset force to open or close, suitable for opening or blocking airflow in vacuum systems. When the valve is closed, the sealing surface of the valve plate is allowed to withstand atmospheric pressure on the upper side and vacuum on the lower side. In this state, after connecting the power supply of the electrical control box, the valve plate can be opened normally.
The applicable working medium is air, non corrosive gas, and gas free of particulate dust.
