These valves are compact air admittance valves with a small flange. The VB valve is manually operated. On rotating the knurled screw cap, the valve disc is lifted off the seating, and air enters through the holes. The valve disc is rotatable. Therefore the valve seat seal is prevented against wear during opening and closing. The VB M-B electronic solenoid valves have a 2.4 ,, orifice diameter and are frequently used for remote-controlled systems (such as interlocking systems and inert gas flushing) when operated by the CVC 3000, VNC 2, or DCP 3000 controllers via the VACUU·BUS® control connection. The gas inlet has a tubing connection, e.g., for inert gas. Larger valves are avilable on request.
