Safety Warning

Description complète du produit

The BDV Series diaphragm valve enables precise control of gas and liquid distribution in semiconductor manufacturing processes.


The BDV is a positive retraction diaphragm valve that features a flexible tied-diaphragm design to control flow of the media. When the valve is actuated, the diaphragm moves up or down. In the open position, the diaphragm lifts, allowing the media to flow. In the closed position, it seals against a valve seat, stopping the flow.


All BDV Series valves are cleaned to exacting semiconductor industry requirements and assembled in class 100 cleanroom environments. Prior to shipping, all valve seals (seat and diaphragm) are 100% Helium leak tested using a mass spectrometer to ensure performance and reliability in demanding UHP applications.
