Valve GDQ-J100
The vacuum valve is powered by hand rotating the handle, compressed air pushing the cylinder and the coil to generate electromagnetic force, which is connected with the valve plate through the mechanism and drives the valve plate to open and close. G series vacuum valves are mainly used in semiconductor, photovoltaic, new energy, medicine, scientific research laboratory, machinery, electronics and other industries.
