Technical Data Sheet: 3″ 150LB PFA Fully Internal Lined Butterfly Valve
- Product Description
This 3-inch, Class 150 flanged (Wafer/Lug) butterfly valve features a body and disc fully encapsulated with PFA (Perfluoroalkoxy) lining. It is specifically designed for highly corrosive chemicals, high-purity media, and severe service conditions, ensuring absolute isolation of the metal components from the process fluid and achieving bi-directional zero leakage.

- Pressure-Temperature Ratings
(Based on Class 150LB and PFA mechanical properties, typical values)
Working Temperature | Maximum Allowable Working Pressure |
-29°C ~ +50°C (-20°F ~ +122°F) | 16.0 bar (232 psi) |
+100°C (212°F) | 14.0 bar (203 psi) |
+150°C (302°F) | 11.0 bar (159 psi) |
+180°C (356°F) | 8.5 bar (123 psi) |
*Note: Final pressure-temperature ratings must comply with ASME B16.34 and the lining manufacturer’s specific data.*
- ویژگیهای کلیدی
- Full Isolation: The body and disc are completely encapsulated with PFA, eliminating any contact between the metal and the media. Provides superior anti-corrosion performance.
- Low Torque Operation: The extremely low friction coefficient of the PFA surface, combined with PTFE bearings, results in low operating torque and prevents sticking.
- Bi-directional Sealing: The spherically machined disc matched with the integrated PFA seat ensures bubble-tight sealing in both directions.
- Blow-out Proof Stem: Features an integral safety step design, preventing the stem from being ejected under high pressure or differential pressure.
- Standardized Mounting: The top flange adheres to ISO 5211 standards, allowing direct mounting of various actuators without the need for complex brackets.
- Precautions & Notes
- Slurry/Media: Avoid media containing hard solid particles, as this may scratch or damage the PFA lining surface.
- Installation: Flange bolts must be tightened evenly and symmetrically. The Lug-style design allows for downstream pipe disconnection while the upstream side remains pressurized.
- Storage: Valves should be stored in a dry, ventilated indoor environment, slightly open, protected from direct sunlight and any physical impact that could damage the lining.
