Sanitary Three-piece Butterfly Valve

Our Sanitary Three-piece Butterfly Valve is designed to regulate and isolate fluid flow with high precision, while maintaining the highest level of hygiene. The three-piece structure allows for easy disassembly, cleaning, and maintenance, eliminating dead corners that could harbor contaminants. Suitable for both manual and pneumatic operation, it is compatible with a wide range of media, including water, dairy products, beverages,pharmaceutical liquids, cosmetics, and corrosive chemicals, providing versatile solutions for various hygienic processing scenarios.

1.Superior Hygiene Performance : Valve body and disc are made of food-grade AISI 304/316L stainless steel (EN 1.4301/1.4404), with high-precision polishing treatment (Ra 0.4-0.8μm as standard) on both inner and outer surfaces. No dead corners or media accumulation areas, effectively preventing bacterial growth and ensuring fluid purity-fully compliant with FDA 21 CFR 177.2600 standards.

2.Detachable Three-piece Design : The valve body is divided into three detachable parts, allowing quick disassembly without removing the entire pipeline. This design simplifies cleaning (compatible with CIP/SIP cleaning processes), maintenance, and replacement of internal components, saving time and labor costs for your production line.

3.Excellent Sealing & Corrosion Resistance : Equipped with high-quality sealing gaskets (EPDM as standard, optional Silicone, FKM/Viton, PTFE), which are FDA-certified and resistant to high temperature, acid, alkali, and various corrosive media. The precision-machined valve disc and seat ensure tight sealing, zero leakage, and long service life even under harsh working conditions.

4.Flexible Operation & Wide Compatibility : Available in manual (pull handle, multi-position plastic/stainless steel handle) and pneumatic (single-acting/double-acting) operation modes, with interchangeable actuators for easy adaptation to different production needs. The valve supports multiple connection types, including tri-clamp, butt-weld, and threaded, compatible with DIN, 3A, SMS, ISO/IDF, RJT standards.

5.Precision Machining & Reliable Quality : Adopting full CNC one-time machining technology, ensuring high dimensional accuracy and stable performance. Every valve undergoes 100% pressure testing before shipment to ensure no leakage, with a service life comparable to imported products and an 18-month warranty for normal use.

6.Cost-Effective & Space-Saving : Compared with traditional ball valves, our butterfly valve is 75% lighter, reducing strain on piping systems and saving valuable space in crowded production areas. For large-diameter applications (2 inches and above), it is 30-50% more economical, helping you reduce procurement costs while maintaining high performance.

- Food & Beverage Industry : Dairy products, fruit juice, beer, wine, soft drinks, meat processing, and food additives-ensuring contamination-free fluid transfer and mixing.

- Pharmaceutical Industry : Pharmaceutical liquids, vaccines, blood products, sterile production lines, and bioreactors-meeting GMP standards and ensuring the purity of medical products.

- Cosmetic & Personal Care Industry : Cosmetics, skin care products, and toiletries-preventing cross-contamination and maintaining product quality.

- Chemical & Biochemical Industry : Corrosive chemicals, clean steam, and biochemical reagents-resisting corrosion and ensuring safe fluid control.

- Other Hygienic Applications : Purified water systems, sterile air pipelines, and other scenarios requiring high hygiene standards and efficient flow control.
