The stainless steel spherical housing with zero dead space offers the ideal flow conditions. The hygiene-committed design of BIOVENT® control valves is CIP capable and ensures that any residue is drained. This makes the valves easy to clean and prevents damage caused by oxidation as well as media from settling. The housing components are connected by means of stainless steel clamping rings, which facilitates maintenance and allows different housing and connection types to be used.
