PFA Fully Lined Butterfly Valves Lugged

Description

TECHNICAL DATA SHEET

Fully Lined PFA Butterfly Valve
Series: PN10/PN16, Class 150LB
Models: Wafer Type / Lug Type / Two-piece Body

1. PRODUCT OVERVIEW

Fully lined PFA butterfly valves are engineered for bidirectional bubble-tight shutoff and flow control in highly corrosive chemical, semiconductor, pharmaceutical, and ultra-pure water applications . The valve features a precision-molded PFA (Perfluoroalkoxy) liner fully encapsulating all wetted parts, ensuring zero metal contact with process media .

Key Features:

• Full PFA Lining: Body cavity, disc, and stem contact surfaces are completely encapsulated with PFA, providing unsurpassed resistance to corrosion, permeation, and microbial contamination .
• Bidirectional Zero Leakage: Spherically molded PFA liner and matching disc interface form a tight bidirectional seal; energized backup liner maintains uniform sealing pressure .
• Blow-out Proof One-piece Disc/Stem: Integrally designed disc and stem eliminates mechanical joints, preventing damage to PFA lining and ensuring vacuum service capability .
• ISO 5211 Actuator Mounting: Top flange conforms to ISO 5211 for direct mounting of manual, electric, or pneumatic actuators without brackets .
• Advanced Stem Sealing System: Live-loaded, self-adjusting stem seal (e.g., Acriseal™) minimizes fugitive emissions, compliant with ISO 15848-1/2 .
• End of Line Service Capability: Elastomer backup liner enables downstream dismantling at full working pressure .
• Spark Tested Lining: All lined components undergo 15KV high-voltage spark test to ensure pinhole-free integrity .

5. DIMENSIONS & CONNECTIONS (PN10 / 150LB – Wafer Type)

Unit: mm (Reference values, consult factory for precise dimensions)

Notes:

• Face-to-face dimensions conform to ISO 5752 Series 20 / EN 558 Series 20 / API 609 .
• Lug type versions available with threaded bolt holes .
• For ASME B16.5 Class 150LB, JIS 10K, or other flange standards, dimensions vary accordingly .

6. PRESSURE-TEMPERATURE RATING (PFA Lined)

*Note: Extended temperature range up to +200°C achievable with special PFA/TFM compounds, with reduced pressure rating . Consult factory for specific P/T diagrams.*

Vacuum Service: Suitable for full vacuum up to +160°C with silicone rubber backup sealing .

7. OPERATING TORQUE (REFERENCE @ 25°C WATER)

Application Factors:

• Dry gases: Multiply by 1.25
• Viscous media (>100 cP): Multiply by 1.3 – 1.5
• Slurries/crystalline media: Multiply by 1.5 – 2.0
• Operating frequency > 50 cycles/day: Add 25% safety margin
