A corrosion-resistant valve designed for highly aggressive media, combining turbine-driven efficiency with fluoropolymer-lined durability.
Structural & Design Features
1. Turbine Drive System
- Equipped with a worm gear mechanism for low operating torque and smooth opening/closing, ideal for large-diameter valves or frequent operation.
- Compatible with manual, electric, or pneumatic actuators for flexible control.
2. Fluoropolymer Lining & Corrosion Resistance
- Valve body lined with fluoroplastics (e.g., PTFE, FEP, PFA), and butterfly disc coated with fluorine material. Resists strong acids, alkalis, organic solvents, and oxidizers. Operating temperature: **-50°C to 150°C**.
- Integrated liner-and-seat design isolates media from metal components, preventing corrosion.
3. Sealing Performance
- Four-stage sealing structure: Combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves for bidirectional zero-leakage sealing.
- Double eccentric or centerline design: Enhanced sealing reliability via increasing seal compression during closure (refer to models in sources).
Technical Parameters & Models
1. Key Models
- Common models: D341PO-16P, D341F4, D341F46
- D3: Turbine-driven; "41": Flanged connection; "F4/F46": Fluoropolymer type.
- Size range: DN40 to DN1200; Pressure rating: PN10-PN16
2. Material Configuration
- Body/Disc: Stainless steel (CF8, CF8M), cast steel, or ductile iron with anti-corrosion coating (e.g., epoxy paint).
- Shaft: 1Cr13, 40Cr, or stainless steel for wear and corrosion resistance.
Applications
- Industries: Chemical, petrochemical, pharmaceuticals, food processing, water treatment, energy (power plants, metallurgy).
- Media: Suitable for sulfuric acid, strong alkalis, wastewater, gases, and other aggressive fluids.
Advantages & Features
1. Installation Flexibility
- Omnidirectional installation with no flow direction restrictions, adaptable to complex piping layouts.
2. Maintenance & Longevity
- Replaceable seals extend service life; Fluoropolymer linings can be upgraded for different media.
3. Compliance
- Manufactured to GB/T 12238 and other international/domestic standards.
V. Example Models
- D341F46-16P: Stainless steel body, PN16 pressure rating, DN40-DN1200, for highly corrosive media.
- D341PO: Fully lined structure, FEP-coated disc, withstands temperatures up to 150°C.
