Spherical valve
August 17, 2016
The Roto-Disc II spherical valve is used where the valve outlet must mate to a downstream flange that matches the valveās inlet orifice. When provided with an optional inlet flange adaptor, the Roto-Disc II valve can mate to common ANSI 150# flanges on the inlet and discharge side. Typical applications include hopper fill and discharge, blender discharge, loss-in-weight feeder refill, bulk bag unloading, and other gravity or low-pressure applications.
