Engineered for the toughest environments, this corrosion-resistant valve excels in handling highly aggressive media. Combining the precision of a turbine-driven system with the durability of a fluoropolymer-lined structure, it redefines efficiency and longevity.
Structural & Design Features
1. Turbine Drive System
- Featuring a cutting-edge worm gear mechanism, it ensures effortless operation with low torque, perfect for large-diameter applications or frequent use.
- Versatile in its control options, seamlessly compatible with manual, electric, or pneumatic actuators for supreme adaptability.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve's body is expertly lined with top-tier fluoroplastics like PTFE, FEP, and PFA, with the butterfly disc fortified in a fluorine coat. It triumphs against potent acids, robust alkalis, organic solvents, and oxidizers, operating flawlessly from **-50°C to 150°C**.
- The ingenious liner-and-seat design isolates corrosive media, safeguarding all metal components from corrosion potential.
3. Sealing Performance
- Employing a sophisticated four-stage sealing structure, it masterfully combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves for unparalleled bidirectional zero-leakage sealing.
- Utilize double eccentric or centerline configurations, enhancing sealing reliability by optimizing seal compression during closure, adaptable to specialized model needs.
Technical Parameters & Models
1. Key Models
- Premier models include: D341PO-16P, D341F4, and D341F46, each crafted for distinct applications.
- Decoding the model: 'D3' signifies turbine drive, '41' indicates a flanged connection, while 'F4/F46' specifies the fluoropolymer type.
- Available in sizes ranging from DN40 to DN1200, with pressure ratings of PN10-PN16, accommodating diverse operational needs.
2. Material Configuration
- Select from stainless steel (CF8, CF8M), cast steel, or ductile iron, all treated with anti-corrosion coatings such as epoxy paint for robust protection.
- Shafts manufactured from 1Cr13, 40Cr, or premium stainless steel enhance wear and corrosion resistance.
Applications
- Perfectly suited for sectors like chemical processing, petrochemical industries, pharmaceuticals, food, water treatment, and energy sectors including power plants and metallurgy.
- Handles a wide array of media, including sulfuric acid, strong alkalis, wastewater, gases, and numerous other aggressive fluids.
Advantages & Features
1. Installation Flexibility
- Offers omnidirectional installation freedom with no flow direction constraints, making it suitable for complex piping systems.
2. Maintenance & Longevity
- With replaceable seals, the valve promises extended service life, and fluoropolymer linings can be customized for different media types.
3. Compliance
- Adheres rigorously to GB/T 12238 and other key international and domestic standards, ensuring quality and reliability.
V. Example Models
- Model D341F46-16P features a stainless steel body with a PN16 pressure rating, covering DN40-DN1200 sizes, ideal for highly corrosive environments.
- The D341PO model boasts a fully lined structure with an FEP-coated disc, capable of enduring temperatures as high as 150°C.
