Introducing our Stainless Steel Butterfly Valve with NBR Seat and Flanged Design. This innovative valve delivers exceptional corrosion resistance and is expertly crafted to handle highly aggressive media. It combines turbine-driven efficiency with the unparalleled durability of fluoropolymer lining, setting a new standard for performance and reliability.
Structural & Design Features
1. Turbine Drive System
- Our valve is outfitted with a sophisticated worm gear mechanism, ensuring low operating torque and seamless opening/closing. This feature is especially advantageous for managing large-diameter valves or operations that require frequent cycling.
- Enjoy unrivaled flexibility in control with compatibility for manual, electric, or pneumatic actuators, making this valve a versatile choice for various applications.
2. Fluoropolymer Lining & Corrosion Resistance
- The valve body is enhanced with a premium fluoroplastic lining (such as PTFE, FEP, PFA), while the butterfly disc is coated with robust fluorine material. This ensures extraordinary resistance against potent acids, alkalis, organic solvents, and oxidizers. It operates reliably within a temperature range of **-50°C to 150°C**.
- Our innovative integrated liner-and-seat design effectively isolates media from metal parts, thereby preventing corrosion and extending the valve's lifespan.
3. Sealing Performance
- Experience unparalleled sealing with our four-stage sealing structure. This advanced design integrates shaft transition curves, elastic O-rings, metal gaskets, and elastic seat grooves, guaranteeing bidirectional zero-leakage sealing.
- Choose between a double eccentric or centerline design to enhance sealing reliability. These designs increase seal compression during closure for optimal performance (refer to models in sources for detailed information).
Technical Parameters & Models
1. Key Models
- Explore our popular models: D341PO-16P, D341F4, D341F46, each designed to meet specific operational needs.
- Deciphering model specifics: 'D3' signifies turbine-driven; '41' denotes flanged connection; 'F4/F46' refers to the fluoropolymer type used.
- Available in a comprehensive size range from DN40 to DN1200, with a pressure rating of PN10-PN16, catering to diverse industrial requirements.
2. Material Configuration
- Constructed from premium materials: The body and disc are available in stainless steel (CF8, CF8M), cast steel, or ductile iron, optionally coated with anti-corrosion treatments like epoxy paint.
- The shaft is crafted from highly durable materials such as 1Cr13, 40Cr, or stainless steel, ensuring superior wear and corrosion resistance.
Applications
