CBF04-TF01--Operation and Maintenance Manual DOWMLOAD

PTFE Lined Flanged Butterfly Valves-2

Key Features:

1. Reinforced PTFE Lining System

Enhanced Thickness Design: 3-4mm PTFE lining in high-wear zones provides superior abrasion resistance against solid particles up to 40% concentration
Complete Media Isolation: Full-body PTFE encapsulation prevents metal contact with abrasive and corrosive media
Temperature Resilience: Maintains lining integrity from **-35℃to 200℃** in continuous abrasive service

2. Flanged Connection Reliability

Robust Flange Design: ANSI B16.5 Class 150# or DIN EN 1092-1 PN16 flanges with reinforced neck construction
Secure Mounting: Serrated flange faces prevent gasket blowout under pressure fluctuations and vibration
Maintenance Access: Bolted flange connection enables easy internal inspection and component replacement

3.Abrasion-Resistant Construction

Wear Zone Reinforcement: Additional PTFE thickness at disc edges and seat contact areas extends service life by 200% compared to standard lined valves
Particle Deflection Design: Optimized disc geometry redirects abrasive particles away from critical sealing surfaces
Surface Hardness: PTFE lining with filler reinforcement achieves Shore D 65 hardness for enhanced wear resistance

4. Advanced Sealing Technology

Zero Leakage Performance: PTFE-to-PTFE seating system achieves EN 12266-1 Class A bubble-tight shutoff
Abrasion-Compensating Design: Resilient PTFE seating maintains seal integrity as wear occurs
Fire-Safe Option: Available with API 607 compliant secondary metal seals for emergency shutdown
