Vacuum Valve: Vacuum Butterfly Valve
A butterfly valve has high flow conductivity for turn on or cut off the vacuum airflow called vacuum butterfly valve. Vacuum butterfly valve and vacuum ball valve are two types of common vacuum valves. The applicable media is air and non-corrosive gas. In order to get the control automatically, solenoid valve and position indicator are optional device.
