Flush bottom valves (referred to as Tank valve, Angle bottom valve, Bottom drain valve, Flush mount valve etc.) are designed to provide drainage and dead space free shutoff for reactors, vessels, autoclaves and storage tanks. The dead space free shutoff is accomplished by placing the valve seat flush with the bottom of the vessel. This eliminates any buildup of product within the vessel nozzle itself.

Advantage of Disc type is short stroke for open/close operation. Air cylinder operation is usual for saving labor.

Ram ( Piston ) type valves are suitable for polymer application.

Teflon(R) coating and lining available.
For corrosion resistance, chemical resistance, and adhesion prevention of impurities.
Not only for Polymer, but also Pharmaceutical, food application
