High Vacuum Pneumatic Angle Valve

Pneumatic Type EVGDQ Series High Vacuum Angle Valve, DN16-DN50

The pneumatic valve is powered by compressed air to open or close the valve plate. When the air source stops, the valve plate will automatically close by the spring force.

The medium of the valve is air and a few corrosive gases.
