Mucon Oyster Hygienic Super Clean Valve

The Mucon Oyster Hygienic Super Clean Valve conforms to best practice and FDA norms. It is the ideal Clean In Place (CIP) solution where frequent cleaning is required and where the valve itself does not need to be dismantled from the machine to be cleaned together with the rest of the plant as part of the normal cleaning regime.


The Mucon Oyster Super Clean Valve is superior to traditional stainless steel Butterfly valves as it has no ‘dead’ areas where product material can be trapped. As a consequence there is no need to dismantle the valve to completely clean all contact surfaces.


he Oyster Super Clean valve is FDA compliant and is suitable for handling;

  • Powders
  • Granules
  • Gels
  • Liquids

In the Pharmaceutical, Chemical and Food sectors


  • Valve bodies can be produced in Hastelloy HC22
  • Ceramic sandblasting or electro-polishing is available upon request
  • ATEX certification


  • The Shaft on the Oyster Super Clean valve does not pass through a gasket. Tightness is achieved by means of an O-Ring making it easier for the operator to clean the valve.
  • The valve stem which actuates the Disc with traditional Butterfly valves has to pass through a hole in the seal / seat gasket. As this area around the hole is constantly in tight contact with the seal / seat gasket it is very difficult to ensure all contact surfaces are cleaned without completely dismantling the valve.
  • As the OSC Super Clean valve has no dead areas there is;
    • Less production down time
    • Productivity is increased
    • Simpler cleaning process

Reduced operating and manpower costs

Should the Super Clean valve need to be stripped down, this can be achieved quickly and easily without the need for tools.

  • The Disc movement of the Oyster Super Clean valve prevents ‘Bridge’ formation
