A heavy spherical valve that won't gum up, jam, or pinch your product. Features a bubble-tight sealing system that is ideal for pressure up to 100 psi or for full vacuum processing.

Three features make Roto-Disc truly unique:

1. Smaller flange sizes make Roto-Disc well suited for a wide range of industrial applications.
   
   
2. Heavy duty materials -- ductile iron, aluminum, or stainless steel -- make it ideal for your toughest applications.
   
   
3. Disc to seat adjustment is dramatically easier, faster, and more precise.

Sticky and gummy substances, abrasives, pellets, granular substances. Almost anything that runs through a process line can be run through this amazing workhorse valve -- day after day -- with incredibly low maintenance.
