STAINLESS STEEL Triple Offset PTFE Seat Ring Butterfly Valve

The stainless steel triple offset PTFE seat ring butterfly valve operates by rotating the disc around three offset axes, which separates the disc from the seat during opening and closing. When the actuator—manual, electric, or pneumatic—rotates the disc parallel to the flow, the valve opens, allowing fluid to pass with minimal pressure loss. During closing, the disc moves along the offsets and presses against the PTFE seat ring, creating a tight, uniform seal that prevents leakage. The triple-offset design reduces friction and wear, enhancing durability and reliability, while the stainless steel body ensures corrosion resistance, making it suitable for chemical, water, and industrial piping systems.

Valve parts

• Triple-offset design minimizes friction between disc and seat, ensuring tight sealing and extended service life even under high pressure and temperature conditions.
• PTFE seat ring provides excellent chemical resistance, preventing leakage and ensuring reliable performance with corrosive or aggressive media.
• Stainless steel body (304/316L) offers superior corrosion resistance, mechanical strength, and durability for industrial and chemical applications.
• Suitable for on/off and throttling operations, allowing precise flow control with minimal pressure drop across the valve.
• Compact and robust construction simplifies installation, maintenance, and integration into various piping systems, ensuring efficient and safe operation

The stainless steel sanitary three-piece manual butterfly valve with lever handle is mainly used in industries with high requirements for hygiene standards. The following are several typical industries. Food processing: control fluid flow to ensure that the production environment meets hygiene standards. Beverage production: regulate beverage flow to prevent contamination and ensure cleanliness and hygiene. Dairy products: control emulsion flow to ensure that pipes and valves are clean and free of residue. Pharmaceutical industry: regulate liquid delivery to meet strict hygiene requirements. Biopharmaceuticals: control the flow of raw materials to ensure no pollution and ensure stable production. Chemical industry: used for fluid control to ensure high standards of cleanliness and safety requirements.
