Introducing an exceptional corrosion-resistant valve, expertly designed for managing the most aggressive media. This product masterfully combines turbine-driven efficiency with the unmatched durability of a fluoropolymer lining.
Structural & Design Features
1. Turbine Drive System
- Engineered with a sophisticated worm gear mechanism, this system ensures low operating torque and facilitates smooth opening and closing. Perfectly suited for large-diameter valves or applications requiring frequent operation.
- Versatile compatibility with manual, electric, or pneumatic actuators provides unparalleled flexibility in control.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve's body is expertly lined with high-performance fluoroplastics such as PTFE, FEP, and PFA. This lining, along with the fluorine-coated butterfly disc, offers exceptional resistance to strong acids, alkalis, organic solvents, and oxidizers, functioning efficiently within a wide temperature range of **-50°C to 150°C**.
- The innovative integrated liner-and-seat design effectively isolates the media from metal components, thereby preventing corrosion and ensuring longevity.
3. Sealing Performance
- Features a robust four-stage sealing structure that combines shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves, ensuring bidirectional zero-leakage sealing.
- Choose between a double eccentric or centerline design to enhance sealing reliability by increasing seal compression during closure. For more specifics, refer to model sources.
Technical Parameters & Models
1. Key Models
- Our line includes popular models such as D341PO-16P, D341F4, and D341F46.
- Deciphering model codes: 'D3' denotes turbine-driven, '41' indicates flanged connection, and 'F4/F46' refers to the type of fluoropolymer used.
- Size options range from DN40 to DN1200, with pressure ratings between PN10 and PN16.
2. Material Configuration
- Constructed with quality materials: Choose from stainless steel (CF8, CF8M), cast steel, or ductile iron, each with an anti-corrosion coating like epoxy paint.
- Shafts are crafted from 1Cr13, 40Cr, or stainless steel, ensuring both wear and corrosion resistance.
Applications
- Widely adopted across diverse industries such as chemical, petrochemical, pharmaceuticals, food processing, water treatment, and energy sectors including power plants and metallurgy.
- Ideal for handling media like sulfuric acid, strong alkalis, wastewater, gases, and other aggressive fluids.
Advantages & Features
1. Installation Flexibility
- Enjoy the benefits of omnidirectional installation with no flow direction restrictions, making it adaptable to complex piping layouts.
2. Maintenance & Longevity
- Designed for longevity with replaceable seals to extend service life. Plus, fluoropolymer linings can be upgraded to suit different media needs.
3. Compliance
- Proudly manufactured in compliance with GB/T 12238 and a host of other international and domestic standards.
V. Example Models
- Model D341F46-16P features a robust stainless steel body, supports a PN16 pressure rating, and accommodates sizes from DN40 to DN1200, specifically designed for highly corrosive media.
- The D341PO model offers a fully lined structure with an FEP-coated disc, capable of withstanding temperatures up to 150°C.
