Oyster Hygienic Composite


The ideal choice for the discharge and volumetric dosing of powders, particularly in pack-off system. The ingenious design of the valve ensures optimal filling rates and dosing accuracy. It can be easily customised to suit individual customer requirements

The standard MUCON range of stainless steel hygienic Butterfly valves offers an outstanding technological solution to the handling and control of powders, granules and liquids. The MUCON range is manufactured to exacting tolerances and finished to the highest, most stringent hygienic requirements.

Mucon stainless steel hygienic Butterfly valves have been specifically designed for use in the Pharmaceutical, Food and Dairy sectors, where the utmost level of hygiene is paramount.

Principle of Operation

The Mucon Oyster Composite valve is designed to dispense product volumetrically in order to achieve accurate feed weights.

Product discharge occurs in two phases:

  1. The bulk discharge phase during which the main leaf is opened by a pneumatic actuator and the valve works like a butterfly valve. As the target weight is approached, the main leaf is closed.
  2. The fine dosing phase during which the main leaf remains closed and the dosing ball is operated by means of a pneumatic 180° actuator. As the ball rotates back and forth, it's lobed surface dispenses product volumetrically in small amounts, enabling a very accurate target weight to be achieved.
