Sanitary Welded Butterfly Valve

Our Sanitary Welded Butterfly Valve is a hygienic fluid control component designed to regulate, shut off, or adjust the flow of liquids, gases, or semi-viscous media in sanitary environments. Adopting a welded connection design, it eliminates dead corners and gaps that are prone to medium accumulation, ensuring no pollution or cross-contamination-making it the ideal choice for industries that require strict compliance with hygiene standards. The valve features a compact structure, lightweight design, and smooth operation, which not only saves installation space but also reduces operational effort and maintenance costs.

1.Welded Connection Design : The butt-welded connection ensures a tight, leak-proof seal between the valve and the pipeline, avoiding the risk of medium leakage and external contamination. The seamless connection also eliminates dead zones, making CIP (Clean-in-Place) and SIP (Sterilize-in-Place) operations more thorough and efficient, greatly reducing cleaning time and labor costs.

2.Durable & Corrosion-Resistant : The valve body, valve disc, and valve stem are all made of high-quality stainless steel 304, 304L, 316, or 316L, which have excellent corrosion resistance, high temperature resistance, and pressure resistance. They can withstand the erosion of acidic, alkaline, and other corrosive media, ensuring long-term stable operation in harsh working environments. The valve seat is available in EPDM, silicone (VMQ), or FPM (Viton) to meet different temperature and medium requirements.

3.Precise Flow Control & Quick Operation : The valve disc adopts a streamlined design, which minimizes flow resistance when fully open, ensuring large flow and energy saving. The 0-90° quarter-turn operation allows for quick opening and closing, and the valve can be fixed at every 15° position for precise flow adjustment-suitable for both on-off control and flow regulation scenarios. The valve stem is equipped with a nylon bushing to reduce friction, making the operation flexible and labor-saving.

4.Easy Maintenance & Long Service Life : The compact and detachable structure allows for quick disassembly and maintenance without removing the entire valve from the pipeline, significantly reducing downtime. All components are rigorously tested, including a fatigue life test of no less than 30,000 times, ensuring reliable performance and a long service life. The surface is polished to be smooth and dust-free, with no burrs, making it easy to clean and maintain.

5.Customizable Specifications : We offer a full range of specifications to meet your diverse needs, with size ranges from 3/4" to 6" (DN15 to DN150), and can customize large-size valves according to your requirements. The driving mode can be manual, pneumatic, or electric, and the pressure rating is up to 1.0MPa (145psi), adapting to different working conditions and process requirements.
