3“ 150LB PFA Fully Internal Lined Butterfly Valves

Technical Data Sheet: 3″ 150LB PFA Fully Internal Lined Butterfly Valve

1. 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.

3. Materials of Construction

4. Performance Data

• Operating Temperature: -29°C to +180°C (-20°F to +356°F)
• Kelas Kebocoran: Bi-directional Zero Leakage (ISO 5208 Rate A / ANSI FCI 70-2 Class VI)
• Suitable Media: Strong acids (Sulfuric, Hydrochloric, Hydrofluoric), strong alkalis, organic solvents, high-purity water, wet chlorine gas, etc.
• Vacuum Service: Applicable, full vacuum rated within -10°C to +160°C (+14°F to +320°F)
• Lining Integrity Test: 100% High Voltage Spark Test (15kV or 10kV DC) performed on every valve to ensure zero pinhole defects.

5. Pressure-Temperature Ratings

(Based on Class 150LB and PFA mechanical properties, typical values)

*Note: Final pressure-temperature ratings must comply with ASME B16.34 and the lining manufacturer’s specific data.*

6. Fitur Utama

• 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.

7. Precautions & Notes

1. Slurry/Media: Avoid media containing hard solid particles, as this may scratch or damage the PFA lining surface.
2. Installation: Flange bolts must be tightened evenly and symmetrically. The Lug-style design allows for downstream pipe disconnection while the upstream side remains pressurized.
3. 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.
