The stainless steel butterfly valve is a corrosion-resistant flow control valve designed to prevent cross-contamination, featuring a lug body for secure flange installation, reliable sealing, and precise on/off or throttling operation in water and industrial pipelines.
The stainless steel 316L lug style anti-mixing water butterfly valve operates by rotating a central disc mounted on a shaft inside the valve body. When the valve is opened, the disc turns parallel to the flow, allowing water to pass smoothly with minimal pressure drop. When closing, the disc rotates perpendicular to the flow and presses firmly against the valve seat, creating a tight seal that prevents leakage and cross-mixing of fluids. The lug-style body allows secure flange installation and supports end-of-line service without removing the opposite flange. The 316L stainless steel construction ensures excellent corrosion resistance, durability, and reliable performance in water treatment, industrial, and sanitary pipeline systems.

● The stainless steel sanitary quick-install duckbill butterfly valve establishes an effective static discharge channel through the conductive spring or conductive coating between the valve body and the butterfly plate to prevent static electricity accumulation caused by fluid friction.
● The stainless steel sanitary quick-install duckbill butterfly valve adopts a removable seal seat structure. The sealing component can be replaced without replacing the entire valve body, which greatly reduces maintenance costs.
● The stainless steel sanitary quick-install duckbill butterfly valve is designed with a double-layer discharge groove at the bottom of the valve body. Even if the seal ring is slightly worn, it can guide the liquid to the external visible area.
● The stainless steel sanitary quick-install duckbill butterfly valve adopts nano-level ultra-precision electrolytic polishing to reduce the surface roughness to within Ra0.2µm, greatly reducing the adhesion of the medium.
● The stainless steel sanitary quick-install duckbill butterfly valve adopts an optimized gear ratio and transmission mechanism design to reduce the torque demand by 30% when manually or pneumatically driven, reducing operating fatigue.
● The stainless steel sanitary quick-install duckbill butterfly valve adopts an integrated molding process to manufacture the butterfly plate, without welding gaps, reducing bacteria breeding points and improving impact resistance.
Stainless steel sanitary quick-install duckbill butterfly valves are widely used in the following industries: Food processing industry: used to control liquid discharge, meet sanitary standards, and prevent pollution. Pharmaceutical industry: used to ensure that fluids are free of contamination and meet sanitary regulations such as GMP. Dairy industry: prevent liquid residue and ensure product quality and safety. Bioengineering industry: suitable for fluid transportation and discharge with high hygienic requirements. Beverage industry: ensure aseptic requirements in the beverage production process and prevent cross contamination. Chemical industry: suitable for conveying corrosive or easily contaminated fluids. Cosmetics industry: used to ensure high cleanliness and safety in cosmetics production.
