Technical Features & Advantages:

1. Premium Stainless Steel Construction

• Complete SS Body: CF8/CF8M (304/316 stainless steel) body provides excellent corrosion resistance against chemicals, chlorides, and atmospheric exposure  

• Durability Assurance: High-grade stainless steel maintains structural integrity under pressure and temperature fluctuations  

2. PTFE Seat Sealing Performance

• Chemical Immunity: Virgin PTFE seat resists acids, alkalis, and solvents across the full pH range (0-14)  

• Zero Leakage: PTFE seating system achieves bubble-tight shutoff per EN 12266-1 Class A standards  

• Temperature Resilience: Maintains sealing integrity from -30°C to 200°C in continuous service

3. Lug-Type Design Benefits

• End-of-Line Service: Threaded lug holes allow direct pipeline mounting without additional nuts  

• Secure Installation: Bolted connection ensures leak-free performance under pressure variations  

• Easy Maintenance: Simplified disassembly for inspection and component replacement

4. Operational Excellence

• Low Torque Operation: Optimized disc design reduces operating torque by 30%  

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

• Visual Indication: Clear position indication for operational safety and convenience
