PTFE/FEP/PFA Lined Flush bottom tank drain valves are designed to provide drainage and dead space free shutoff togeather with corrosion resistance, chemical resistance, and adhesion prevention of impurities for reactors, vessels, autoclaves and storage tanks and are most suitable not only for Polymer, but also Pharmaceutical, food application. 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.
