Introducing a state-of-the-art, corrosion-resistant marvel: the Industrial Stainless Steel Flanged Butterfly Valve with Pneumatic Actuator. Expertly crafted for enduring performance in handling highly aggressive media, this valve masterfully blends turbine-driven efficiency with the unparalleled durability of a fluoropolymer lining.
Structural & Design Features
1. Turbine Drive System
- This sophisticated valve is equipped with a precision-engineered worm gear mechanism, ensuring minimal operating torque and ultra-smooth opening and closing actions. It's a perfect fit for large-diameter valves or applications with frequent use.
- Offering seamless compatibility with manual, electric, or pneumatic actuators, this valve provides exceptional flexibility in control to meet diverse operational requirements.
2. Fluoropolymer Lining & Corrosion Resistance
- Engineered with a robust valve body lined with advanced fluoroplastics such as PTFE, FEP, and PFA, alongside a butterfly disc coated with fluorine material, this valve excels in resisting strong acids, alkalis, organic solvents, and oxidizers. It operates efficiently across a broad temperature range from **-50°C to 150°C**.
- The integrated liner-and-seat design serves as a formidable barrier, effectively isolating media from metal components and thereby preventing any corrosion.
3. Sealing Performance
- Featuring a pioneering four-stage sealing structure, this valve combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves to ensure bidirectional zero-leakage sealing, delivering unmatched sealing performance.
- With a choice of double eccentric or centerline design, seal compression is enhanced during closure, bolstering sealing reliability. Refer to our models in sources for further details.
Technical Parameters & Models
1. Key Models
- Explore our popular models: D341PO-16P, D341F4, D341F46, each designed to meet specific operational needs.
- Model Details: 'D3' indicates turbine-driven; '41' refers to flanged connection; 'F4/F46' denotes the fluoropolymer type.
- Available in sizes ranging from DN40 to DN1200, with a pressure rating of PN10-PN16, accommodating various application demands.
2. Material Configuration
- Constructed using premium materials: Stainless steel (CF8, CF8M), cast steel, or ductile iron, all featuring an anti-corrosion coating like epoxy paint for enhanced durability.
- The shaft is made from 1Cr13, 40Cr, or stainless steel, offering superior wear and corrosion resistance.
Applications
