Introducing an exceptionally robust valve engineered for peak performance even in the most hostile environments. This corrosion-resistant marvel effortlessly combines turbine-driven efficiency with the unparalleled durability of a fluoropolymer lining, ensuring long-lasting, reliable operation amidst highly aggressive media.
Structural & Design Features
1. Turbine Drive System
- Featuring a state-of-the-art worm gear mechanism, this system provides minimal operating torque and ensures smooth, seamless operation whether dealing with large-diameter valves or frequent usage, delivering impeccable control and reliability.
- Designed for versatile control, this valve is fully compatible with an array of actuators, including manual, electric, and pneumatic options, catering to a wide range of operational needs.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve's robust body is fortified with high-performance fluoroplastics such as PTFE, FEP, and PFA, while the butterfly disc boasts a protective fluorine coating. This combination offers formidable resistance against a spectrum of corrosive agents including strong acids, alkalis, organic solvents, and oxidizers, effectively operating within temperatures of **-50°C to 150°C**.
- By integrating a liner-and-seat design, this valve ingeniously isolates the media from metal components, ensuring superior corrosion resistance and enhanced longevity.
3. Sealing Performance
- Employing a sophisticated four-stage sealing structure, this valve features a synergy of shaft transition curves, elastic O-rings, robust metal gaskets, and flexible seat grooves to deliver impeccable bidirectional zero-leakage sealing.
- Choose between a double eccentric or centerline design, both of which bolster sealing reliability by optimizing seal compression during closure, as evidenced in various model references.
Technical Parameters & Models
1. Key Models
- Popular models include the D341PO-16P, D341F4, and D341F46, each tailored for specific functional demands.
- Model breakdown: 'D3' indicates turbine-driven functionality, '41' signifies a flanged connection, while 'F4/F46' specifies the type of fluoropolymer used.
- Available in sizes ranging from DN40 to DN1200, with a pressure rating of PN10-PN16, catering to a broad array of applications.
2. Material Configuration
- Crafted from high-grade stainless steel (CF8, CF8M), cast steel, or ductile iron, each component is treated with anti-corrosion coatings like epoxy paint for enhanced durability and protection.
- The shaft, made from 1Cr13, 40Cr, or stainless steel, is specifically chosen for its superior wear and corrosion resistance, ensuring optimal performance.
Applications
- This versatile valve is indispensable across various industries, including chemical, petrochemical, pharmaceuticals, food processing, water treatment, and energy sectors such as power plants and metallurgy.
- It is adept at handling a variety of aggressive media, from sulfuric acid and strong alkalis to wastewater, gases, and beyond.
Advantages & Features
1. Installation Flexibility
- Offering complete installation flexibility, this valve can be fitted in any direction without flow restrictions, making it perfect for complex piping arrangements.
2. Maintenance & Longevity
- With replaceable seals that extend service life and fluoropolymer linings that can be tailored for different media, this valve ensures longevity and adaptability.
3. Compliance
- Meticulously manufactured to comply with GB/T 12238 and various other international and domestic standards, guaranteeing quality and reliability.
V. Example Models
- The D341F46-16P model features a sturdy stainless steel body, a PN16 pressure rating, and size options from DN40 to DN1200, making it an excellent choice for handling highly corrosive media.
- The D341PO model offers a fully lined structure with an FEP-coated disc that can withstand temperatures reaching up to 150°C, demonstrating its capability to endure extreme conditions.
