Flush Bottom Valve

The Flush Bottom Valves designed by us to provide drainage and dead space free shut off for reactors, vessels and storage tanks. This is accomplished by placing the valve seat flush with the bottom of the vessel, which eliminates any buildup of product within the vessel nozzle itself.

Valve sizes are designated by two numericals, First number stands for size of inlet flange connection that is fixed to the tank or vessel bottom pad, Second number stands for port size as well as outlet pipe and its flange size. Inlet flanges are always one size larger in size than the outlet flanges.
