Mucon Disc Valves.

Born out of a specification for a valve, which encompassed all the advantages found in slide and butterfly valves, but with none of the disadvantages. A radially pivoted arm supports a free-floating disc. The arm allows the disc to swing in an arc towards an angled seating face. The angled face ensures the disc only makes contact at the last moment causing a mild wedging action.


Unlike many conventional slide valves, the Disc Valve does not jam or leak, due to its unique angled seat and floating disc arrangement.


There are five bore sizes and these valves can come with either hand lever or pneumatic actuation. Material options available are, Aluminum Alloy, Cast Iron and Stainless Steel (not available in 300mm bore).


Options include

  • A variety of seal materials to suit the most arduous processor clean down regimes
  • A variety of shaft bearing materials
  • Various coatings are also available for extreme applications
  • Lever locking mechanism
  • Open and closed and intermediate position indication switches
  • Pre-piped and valve mounted control solenoid assemblies


  • There are no slide guides to jam or collect product
  • The shaft is the only item that passes through the body casting andeasily sealed using a proprietary seal assembly
  • A dovetail groove in the seating face locates another proprietary sealensuring a dust tight closure
  • A range of bore sizes are available from 100mm to 300mm, with the outletalways larger than the inlet, ensuring no product hang-up points internally
  • In-situ seal wear adjustment


  • Non jamming action
  • 100% product shut-off
  • Dust Tight
  • Long life, Low Maintenance


Dust explosion prevention or protection may be required on systems handling dry powder or granular materials. To operate without proper explosion venting may result in fire or explosion. check local industrial codes and policies or consult SHAPE.
