Sanitary Three way Butterfly Valve
KINGMAN supplies sanitary T-type 3-way butt-weld butterfly valves. The valve body is forged from SS304 / SS316L stainless steel. Butt-weld ends enable direct welding to pipelines for a robust, leak-tight joint, eliminating leakage risks associated with union or clamp connections.
The valve bore features high-gloss polishing with zero dead space, compatible with CIP cleaning and SIP high-temperature steam sterilization. Three independent hand levers allow separate on-off control for each channel, supporting fluid diversion, bypass, sampling and other process applications.
Seat material options: EPDM, Silicone, Viton, all meeting FDA food contact requirements. Suitable for food & beverage, dairy, biopharmaceutical, clean fluid and liquid cooling systems.

Features
- 3-way flow switching function, a single valve can realize medium diversion, confluence and flow direction switching, simplifying pipeline layout and reducing the total number of valves on the production line.
- Adopt tri-clamp quick connection structure, which supports fast assembly and disassembly without pipeline cutting or welding, greatly facilitating on-site installation, inspection and routine maintenance.
- Sanitary precision polishing for inner flow surface, free of dead corners and stagnant zones, effectively reduces medium residue and lowers risks of bacterial growth and cross-contamination.
- Equipped with food-grade rubber sealing elements, it delivers excellent bubble-tight sealing performance and good resistance to common liquid, acid and alkali media in sanitary production.
- Compact and optimized valve body structure, fitted with ergonomic manual handle for simple operation, enabling flexible and reliable flow direction switching during production.
- Material options of SS304 / SS316L stainless steel, fully manufactured in compliance with 3A, DIN and SMS sanitary standards for food, beverage and biopharmaceutical applications..
Working Principle
Sanitary Tri-clamp 3-way Butterfly Valve: Pull the manual handle to drive the valve stem to rotate, and then drive the internal high-precision butterfly plate to rotate inside the valve body, which changes the communication state of the three ports. By adjusting the rotation angle of the butterfly plate, Sanitary Tri-clamp 3-way Butterfly Valve can switch between different flow paths freely to realize medium diversion, confluence or cut-off, satisfying various process switching requirements in sanitary production. The food-grade sanitary sealing ring fits tightly with the butterfly plate surface under uniform pressing force, forming reliable bubble-tight sealing to prevent medium leakage and avoid cross-contamination between different material streams. Tri-clamp joints match standard pipeline ferrules and sanitary gaskets, allowing quick assembly and disassembly of the pipeline without cutting or rewelding. It is convenient for internal inspection, seal replacement and thorough CIP/SIP cleaning.
