Technical Features & Performance Advantages:

1. CF8M Stainless Steel Disc Excellence

• Superior Corrosion Resistance: 316 stainless steel composition provides excellent protection against chemicals, chlorides, and corrosive media  

• Mechanical Durability: High-strength disc maintains structural integrity under pressure and thermal cycling conditions  

• Precision Machining: Optimized disc profile ensures smooth operation and perfect seating alignment  

2. PTFE Seat Sealing Performance

• Chemical Inertness: Virgin PTFE seat resists virtually all chemicals across the full pH spectrum (0-14)  

• Zero Leakage Assurance: PTFE-to-disc contact achieves bubble-tight shutoff per EN 12266-1 Class A standards  

• Temperature Resilience: Maintains sealing integrity from -35℃ to 200℃ without degradation

3. Hand Lever Operational Efficiency

• Quick 90°Operation: Lever mechanism enables rapid open/close control with minimal effort  

• Visual Position Indication: Clear open/closed/setting positions for operational safety  

• Torque Optimization: Low-friction design reduces operating force by 35% compared to standard valves

4. Wafer Space-Saving Design

• Compact & Lightweight: 40% reduction in weight and space requirements versus lug-type valves  

• Easy Installation: Simple insertion between ANSI B16.5 or DIN EN 1092-1 flanges  

• Cost Efficiency: Lower material and installation costs without performance compromise

5. Operational Efficiency

• Multiple Actuation：Compatible with manual lever, gear operator, or ISO 5211 standard actuators

• Maintenance-Free：Self-lubricating bearings and corrosion-resistant components minimize service requirements
