Rubber Lined Dual Plate Wafer Check Valve Silent Check Valve for Corrosive Services-1

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

EPDM Vs. PTFE: How To Select The Right Valve Seat Material

This technical article compares EPDM, NBR, and PTFE valve seat materials for industrial applications. It outlines the advantages of elastomers (EPDM for water, NBR for oils) and the necessity of PTFE for aggressive chemicals and temperatures up to 200°C. Crucially, it clarifies the engineering difference between a "PTFE seated valve" and a "PTFE fully lined valve." The guide includes a material selection matrix and concludes with Tianjin Worlds Valve's manufacturing capabilities and CE/PED, WRAS, and ACS certifications.
