Technical Features & Performance Benefits:

1. Complete Rubber Lining Protection

• Full Internal Lining: EPDM, NBR, or natural rubber lining completely isolates metallic components from corrosive media  

• Chemical Resistance: Suitable for acids, alkalis, and chemical solutions across pH 3-11 range  

• Abrasion Resistance: Resilient rubber surface withstands particulate-laden fluids and extends service life  

2. Dual Plate Efficient Design

• Rapid Response: Two spring-assisted plates close instantly upon flow reversal, preventing backflow effectively  

• Low Pressure Drop: Streamlined plate design minimizes flow resistance, reducing energy consumption  

• Silent Operation: Spring-controlled closure eliminates water hammer and pipeline vibration  

3. Wafer Space Optimization

• Compact Construction: 50% lighter and more space-efficient than conventional swing check valves  

• Easy Installation: Simple insertion between ANSI/DIN flanges without additional supports or nuts  

• Cost Savings: Reduced material and installation costs compared to traditional check valve designs

4. Enhanced Sealing Performance

• Bubble-Tight Closure: Rubber-to-rubber seating ensures zero leakage per EN 12266-1 Class A standards  

• Wear Compensation: Resilient seating surfaces maintain seal integrity as wear occurs  

• Temperature Adaptability: Reliable performance from -15°C to 80°C depending on lining material  

5. Quality Assurance & Compliance

• ISO 9001 Certified Manufacturing: Ensures consistent quality control throughout production process

• International Certifications: CE, UKCA, and WRAS approvals guarantee compliance with global market requirements

• Material Traceability: Full documentation and material certifications available for quality verification
