Roto-Disc Inc. now offers a spherical valve for applications where the valve outlet has to mate to a downstream flange that matches the valve’s inlet orifice.

When provided with an optional inlet flange adaptor, the Roto-Disc II can mate to common ANSI 150# flanges on both the inlet and discharge side, eliminating the need for flange and piping transitions while maintaining a full-orifice valve solution. Typical applications include hopper fill and discharge, blender discharge, loss-in-weight feeder re-fill, bulk-bag unloading, and other gravity or low-pressure applications.

Like the Roto-Disc, the Roto-Disc II slices through material build-up and wipes itself clean with each cycle. The sealing surfaces are not exposed to the flow of material and there are no hidden places inside for material to build-up. The valve maintains all other essential features of the original Roto-Disc spherical valve and all spare parts are interchangeable with equivalent sized Roto-Disc valves.

The Roto-Disc II can be supplied in airlock/double-dump assemblies for processing material into and out of differential pressure environments. Roto-Disc also offers a full line of splitter/convergers and piping and flange process transitions.
