Emerson Electric 84021SI Sanitary Control Valve

Emerson's Baumann 84021SI Sanitary Control Valve is a diaphragm-type inline sanitary control valve in the Baumann 84000 family, designed for precise, low-shear control of high-purity fluids in pharmaceutical, biotech, and life-science processes. The 84000 family is designed to meet 3A Sanitary Standards and features electropolished internal surfaces and a USP Class VI diaphragm (PTFE, EPDM-backed), with clean-in-place (CIP) and sanitize-in-place (SIP) compatibility. Its uniquely shaped diaphragm helps minimize shear forces in the flow stream, protecting delicate bio-media and maintaining product consistency. The valve is intended for use in rigorous clean environments and hot CIP/SIP cycles, with an operating temperature capability up to 160°C (320°F) as described in Baumann 84000 literature. The 84021SI model designation identifies a specific version within Emerson's sanitary lineup, corroborated by manufacturer and reseller listings.
