The Sanitary Butterfly Valve for Sanitary applications is a hygienic flow-control 

device made from polished stainless steel with crevice-free surfaces and Tri-Clamp connections, 

designed for contamination-free and reliable operation in food, beverage, and pharmaceutical industries.

Operating Principle:

The  Stainless Steel Butterfly Valve for Sanitary from JIANEN controls flow by means of a rotating disc that opens or closes the passage. It is easy to clean and can be operated either manually or automatically.

Open: The disc rotates to a position parallel to the flow, allowing the product to pass through freely.

Closed: The disc rotates to a position perpendicular to the flow, completely blocking the passage.c

Key Features & Design:

Construction: JIANEN sanitary stainless steel butterfly valves are manufactured from 304 / 316L stainless steel, ensuring excellent corrosion resistance and hygienic performance.

Wetted Surfaces: Mirror-polished (e.g., 32 Ra) to prevent buildup and bacteria, ideal for sanitary applications.

Connections: Tri-Clamp fittings for quick disassembly, inspection, and CIP cleaning.

Disc & Stem: Central disc of the Stainless Steel Butterfly Valve for Sanitary rotates 90°; single-piece design minimizes flow resistance.

Seals: FDA-compliant elastomers (EPDM, Silicone, Viton) ensure leak-free operation.

Operation: Available as hand-operated, pneumatic, or electric butterfly valves from JIANEN, allowing precise and flexible control.
