High-Quality Stainless Steel Flanged Butterfly Valve for Efficient Flow Control

Product Description

Introducing the Stainless Steel Flanged Fluorine-Lined Butterfly Valve with Turbine Head: A true marvel of industrial engineering, perfect for managing aggressive media with style and sophistication.

Product Description

Discover the ultimate in corrosion resistance with our expertly crafted valve. This valve is a powerhouse of durability and efficiency, designed for handling highly aggressive media. The fusion of a turbine-driven mechanism with a robust fluoropolymer lining ensures exceptional performance.

Structural & Design Features
1. Turbine Drive System
- This innovative system harnesses a worm gear mechanism to deliver low operating torque and seamless operation. It's the perfect choice for large-diameter valves or applications requiring frequent operation.
- Enjoy the ultimate in versatility with compatibility for manual, electric, or pneumatic actuators, allowing for flexible control tailored to your needs.

2. Fluoropolymer Lining & Corrosion Resistance
- Engineered with a body lined in high-grade fluoroplastics such as PTFE, FEP, and PFA, and a butterfly disc coated with top-tier fluorine material. This valve resists the most formidable acids, alkalis, organic solvents, and oxidizers. Operational from **-50°C to 150°C**.
- The integrated liner-and-seat design ensures media is isolated from metal components, providing unparalleled corrosion prevention.

3. Sealing Performance
- Our advanced four-stage sealing structure combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves to achieve bidirectional zero-leakage sealing.
- With a double eccentric or centerline design, this valve enhances sealing reliability by increasing seal compression during closure, as demonstrated in our sourced models.


Technical Parameters & Models
1. Key Models
- Highlighting our popular models: D341PO-16P, D341F4, D341F46, known for their reliability and excellence.
- Understanding the nomenclature: 'D3' indicates turbine-driven; '41' refers to flanged connection; 'F4/F46' highlights the fluoropolymer type.
- Available in size range from DN40 to DN1200, with a pressure rating of PN10-PN16 to meet various requirements.

2. Material Configuration
- Constructed with a body/disc of durable stainless steel (CF8, CF8M), cast steel, or ductile iron, all featuring an anti-corrosion coating like epoxy paint.
- The shaft is crafted from robust materials like 1Cr13, 40Cr, or stainless steel, ensuring both wear and corrosion resistance.


Applications
- Widely used across industries such as chemical, petrochemical, pharmaceuticals, food processing, water treatment, and energy sectors including power plants and metallurgy.
- Ideal for handling aggressive media such as sulfuric acid, strong alkalis, wastewater, gases, and other challenging fluids.

Advantages & Features
1. Installation Flexibility
- Offers omnidirectional installation with no restrictions on flow direction, making it adaptable to complex piping layouts.
2. Maintenance & Longevity
- With replaceable seals that extend the valve's service life and upgradable fluoropolymer linings for various media, maintenance is a breeze.
3. Compliance
- Proudly manufactured to meet GB/T 12238 standards and other international/domestic regulations, ensuring top quality and safety.


V. Example Models
- The D341F46-16P showcases a stainless steel body, PN16 pressure rating, and suitability for highly corrosive media across DN40-DN1200 sizes.
- The D341PO model features a fully lined structure with an FEP-coated disc, capable of withstanding temperatures up to 150°C.
