Product Description

Product Description

Duckbill Butterfly Valve

This stainless steel duckbill butterfly valve, manufactured to strict ANSI/ASME standards, is a high-performance, sanitary flow control component optimized for clean fluid systems and industrial pipelines. The unique streamlined "duckbill" disc design minimizes flow resistance and eliminates dead zones, while the lever-operated 90° quarter-turn mechanism enables quick, precise shut-off and throttling. Ideal for applications demanding high corrosion resistance, easy cleaning, and reliable sealing—from food and pharmaceutical production to chemical processing and water treatment projects that comply with American industry standards.
Key Advantages
1.Duckbill Streamlined Design: Special curved disc shape reduces pressure drop, prevents media stagnation and sediment buildup, and facilitates thorough CIP and SIP cleaning cycles.
2.ANSI Standard Compliance: Built to ANSI Class specifications, ensuring seamless compatibility with American-standard flanges, pipes, and system components for global projects targeting the US market.
3.Reliable Bubble-Tight Sealing: Resilient seat with precision machining creates a tight seal even at low pressure, avoiding leakage of aggressive or hygienic media.
4.Easy & Ergonomic Operation: Extended duckbill-style lever allows for effortless 90° rotation, with optional gearboxes or pneumatic/electric actuators for automated remote control in large-diameter or high-pressure systems.
5.Durable & Low Maintenance: All-stainless steel construction resists rust, chemical attack, and wear; minimal moving parts reduce maintenance frequency and operational costs over the long term.
6.Sanitary & Versatile: Smooth internal surfaces without crevices meet the strictest hygiene standards, while also adapting to harsh industrial media, making it suitable for both sanitary and general industrial applications.
Application Fields
1.Food, beverage, dairy, and brewing production lines
2.Pharmaceutical and biotech processing systems
3.High-purity water, ultrapure water, and wastewater treatment plants
4.Chemical processing, petrochemical, and corrosive fluid transfer pipelines
5.Power plant cooling water and industrial process water circuits
6.Offshore and marine fluid handling systems
