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 .
