Crust Breaker Dome
A dome with a “flat top” is supplied that breaks-up a head of crust above the valve as it rotates open. Leading edge of dome is engaged to seat as typical.

Interior: Clean-In-Place
Spray Nozzle
Wide-angle, high-flow spray nozzles are mounted through the body wall, perpendicular to the valve axis, between flanges.
Nozzles are installed by hand to ensure they are flush with the interior of the body.
Two (2) nozzles are typical, but additional nozzles are possible.
Nozzles can flow liquid cleaning solution or air/gas.

C.I.P. Flush-Port
A sanitary fitting is installed through the body wall, perpendicular to the valve axis, between the flanges.
The fitting is plugged and capped to eliminate a void during normal operation
The cap and plug are removed to allow the spray wand to be inserted for interior cleaning.

Shut-off & Diverter Valve
A Roto-Disc®, Inc. shut-off valve is mated directly above a Roto-Blade® diverter for an integrated shut-off and diverter solution.
Typical applications include: Silo Discharge; Mixer/blender Discharge; Dual Reactor Charging

Wedge Insert
The Wedge Insert option relieves the need for a custom inlet “mating” flange. The wedge is made of PTFE, UHMW, PEEK, or other compatible thermoplastic and is press-fit into the upstream flange, thereby eliminating any hang-up ledges.


Note: Customer to provide mating flange I.D. for press-fit of wedge into mating flange.
