This exceptional valve is engineered to withstand the harshest conditions, crafted for use with highly corrosive media. It merges the power of turbine-driven mechanisms with the durability of fluoropolymer linings, ensuring unparalleled efficiency and longevity.
Structural & Design Features
1. Turbine Drive System
- Our valve boasts a state-of-the-art worm gear mechanism, providing minimal operating torque and effortless operation. This makes it perfect for large-diameter applications or environments requiring frequent valve actuation.
- With compatibility for manual, electric, or pneumatic actuators, it offers unparalleled adaptability and control.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve's body is exquisitely lined with premium fluoropolymers like PTFE, FEP, and PFA, while its butterfly disc is expertly coated with fluorine materials. This combination ensures it can resist the most aggressive substances, including strong acids, alkalis, organic solvents, and oxidizers. Operational temperatures range from a chilling **-50°C** to a scorching **150°C**.
- The integrated liner-and-seat design ingeniously separates the media from metal components, providing superior corrosion protection.
3. Sealing Performance
- Our advanced four-stage sealing structure combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves, delivering flawless bidirectional zero-leakage sealing performance.
- Choose between a double eccentric or centerline design for enhanced sealing reliability, increasing seal compression upon closure.
Technical Parameters & Models
1. Key Models
- Discover our most popular models: D341PO-16P, D341F4, D341F46, each designed to cater to specific needs and conditions.
- Understanding our models is simple: 'D3' indicates turbine-driven, '41' signifies a flanged connection, and 'F4/F46' denotes the fluoropolymer type.
- This versatile valve suits a wide size range from DN40 to DN1200 and a pressure rating of PN10 to PN16.
2. Material Configuration
- Crafted from high-quality stainless steel (CF8, CF8M), cast steel, or ductile iron with a protective anti-corrosion coating, such as epoxy paint.
- Shafts are available in 1Cr13, 40Cr, or stainless steel, ensuring excellent wear and corrosion resistance.
Applications
