Spherical Disc Valves for Solids Processing Applications
Solids and slurries have completely different flow characteristics than liquid and gases, so it’s important to choose a valve for these applications carefully. Some factors to consider include material of construction, seat material, finish, flow control, actuation and mounting arrangements.
The GEMCO spherical disc valve which is related to a full-port ball valve, offers many advantages:
• The spherical disc wipes the material away from the matching radius of the seat to provide sanitary sealing and longer seat life.
• The spherical disc rotates 90 degrees out of the material flow, to allow mass-flow through its full port.
• The under-cut disc segment provides clearance that prevents powder jamming between the disc and housing.
Choosing the best valve for your application results in many benefits including: better performance, lower maintenance costs, and better product quality over the life of the processing equipment.
