Oyster Hygienic Tablet Butterfly Valve – Bolted Body

The flexible leaf is co-molded in FDA compatible silicone and gives the flexibility necessary to ensure no damage to tablets or capsule being processed

The Mucon Oyster Tablet Valve is part of our range of stainless steel hygienic Butterfly valves which offer an outstanding technological solution to the handling and control of tablets, capsules, 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.

Its crevice-free, smooth bore and compact design allows the end user to quickly and effortlessly strip-down the complete Butterfly valve for total cleaning. In this version the valve body is assembled using stainless steel fasteners that ensure a rigid and robust construction. Fasteners are kept to a minimum to ease disassembly for cleaning, but for applications requiring regular cleaning we recommend the Mucon Oyster Compact series fitted with the patented clamshell body clamp.
