Technical Features & Design Advantages:

1. Ductile Iron Body Construction

• Superior Strength: EN-GJS-500-7 ductile iron provides excellent impact resistance and longevity

• Corrosion Protection: 250μm epoxy coating standard (300-400μm optional) for harsh environments  

• Cost-Effective: Delivers cast steel performance at a competitive price point  

2. CF8M Stainless Steel Disc

• Corrosion Resistance: 316 stainless steel composition withstands corrosive media and atmospheric exposure  

• Mechanical Durability: Maintains structural integrity under pressure and temperature variations  

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

3. EPDM Seat Sealing Performance

• Bubble-Tight Shutoff: Achieves zero leakage per EN 12266-1 Class A standards  

• Temperature Flexibility: Suitable for applications from -20°C to 120°C  

• Media Compatibility: Excellent for water, mild chemicals, and industrial fluids  

4. Hand Lever Operation

• Quick 90°Operation: Enables rapid open/close control with visual position indication  

• Low Operating Torque: Optimized design reduces required effort by 30%  

• Position Locking: Integrated locking holes secure valve in fully open or closed positions  

5. Wafer Type Design

• Space Saving: Compact construction reduces installation space requirements by 40%  

• Easy Installation: Simple insertion between ANSI/DIN flanges without additional hardware  

• Weight Reduction: 35% lighter than lug-type valves of similar size
