Key Selection Parameters：1. Model Number BreakdownUnderstanding the model code helps identify the correct configuration:D341X-16RL: Flanged butterfly valve (D3), turbine-operated (41), soft-sealed (X), PN16 pressure rating, 316L stainless steel body (RL) .D343W-16RL: Same but with a hard metal-to-metal seal (W), suitable for higher temperatures and abrasive media.2. Core Technical SpecificationsNominal Diameter: DN80(3inches)Pressure Ratings: PN10, PN16, or Class 150Flange Standard: GB/T9119, HG20592, or EN1092-1 (ensure compatibility with your piping system)Face-to-Face Dimension: Typically 46–114 mm depending on the design standard3.Seat Material: Choose based on media temperature and chemical compatibility:EPDM: -40°C to 120°C, suitable for water and mild chemicals .PTFE: -20°C to 150°C, excellent chemical resistance .Metal (Hard Seal): -29°C to 200°C or higher, for steam, oil, and abrasive fluids .4. Actuation and OperationTurbine Operation:The standard turbine gearbox provides smooth, self-locking manual operation for precise flow control .Optional Actuation:Electric or pneumatic actuators can be specified for automated systems .Selection Notes for Buyers
1.Verify Corrosion Resistance:If your media is seawater or highly acidic, 316L is strongly recommended over 304 to prevent pitting and premature failure .
2.Match Flange Standards:Ensure the valve’s flange drilling (e.g., PN16) matches your existing piping flanges to avoid installation issues .
3.Inspect Sealing Material:For temperatures above 120°C, avoid EPDM and choose PTFE or a hard-sealed design .
4.Request Certifications:Ask for material test reports and pressure test certificates from reputable suppliers to guarantee quality .
The Stainless Steel 316L Turbine Flanged Butterfly Valve DN80 offers excellent corrosion resistance and reliable flow control. In 2026, prices range from ¥670 for a standard soft-sealed model to over ¥2,800 for a premium hard-sealed version. The final cost depends on the sealing material, brand, and certification. Always verify your application’s pressure, temperature, and chemical conditions against the valve’s specifications to ensure safe and long-lasting operation .
