Introducing an exceptional corrosion-resistant valve meticulously crafted for handling the most aggressive media. This valve masterfully merges turbine-driven performance with the unparalleled durability of fluoropolymer lining, ensuring long-lasting reliability.
Structural & Design Features
1. Turbine Drive System
- Our valve boasts a sophisticated worm gear mechanism, providing remarkably low operational torque and ensuring effortless, seamless opening and closing. Perfectly suited for large-diameter valves or scenarios demanding frequent operation.
- Offers compatibility with an array of actuator options, including manual, electric, or pneumatic, granting you flexible and convenient control.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve's robust body is lined with advanced fluoroplastics such as PTFE, FEP, and PFA, with the butterfly disc featuring a protective fluorine coating. It stands resilient against strong acids, alkalis, organic solvents, and oxidizers, operating efficiently in temperatures from **-50°C to 150°C**.
- This innovative liner-and-seat design isolates the media entirely from metallic components, offering superior protection against corrosion.
3. Sealing Performance
- Our state-of-the-art four-stage sealing structure integrates shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves to deliver impeccable bidirectional zero-leakage sealing.
- Featuring a double eccentric or centerline design, enhancing sealing reliability through increased compression during closure. Refer to specific models in our resources for more details.
Technical Parameters & Models
1. Key Models
- Prominent models include D341PO-16P, D341F4, and D341F46, each designed for specific application needs.
- Model D3 signifies turbine-driven capability; '41' denotes flanged connection; 'F4/F46' indicates the fluoropolymer type used.
- Available in sizes ranging from DN40 to DN1200, with pressure ratings of PN10 to PN16 for diverse industrial applications.
2. Material Configuration
- Constructed with superior materials: Stainless steel (CF8, CF8M), cast steel, or ductile iron, each treated with a protective anti-corrosion coating, such as epoxy paint, for enhanced durability.
- Featuring a shaft made from high-grade materials like 1Cr13, 40Cr, or stainless steel, offering exceptional wear and corrosion resistance.
Applications
- Ideal for use in chemical, petrochemical, pharmaceutical industries, as well as food processing, water treatment, and energy sectors, including power plants and metallurgy.
- Efficiently handles sulfuric acid, strong alkalis, wastewater, gases, and other aggressive fluids with ease.
Advantages & Features
1. Installation Flexibility
- Designed for omnidirectional installation without flow direction restrictions, making it adaptable to complex piping layouts.
2. Maintenance & Longevity
- Features replaceable seals to extend service life; the fluoropolymer linings can also be upgraded to accommodate different media requirements.
3. Compliance
- Produces in strict adherence to GB/T 12238 standards and other relevant international and domestic standards, ensuring quality and reliability.
