CBF02-TA01-Operation and Maintenance Manual DOWNLOAD

1. Premium Ductile Iron Construction
Material Excellence:The Material of Ductile iron provides superior tensile strength and impact resistance compared to cast iron
Corrosion Protection: Standard 250μm epoxy coating with optional 300-400μm thickness for enhanced durability
Long Service Life: Robust construction ensures reliable performance through 50,000+ operating cycles
2. Wafer Type Space Optimization
Compact Design: 40% lighter and more space-efficient than lug-type valves, ideal for crowded piping systems
Easy Installation: Simple insertion between ANSI/DIN flanges without additional nuts or bolts
Cost Savings: Reduced material and installation expenses without compromising performance
3. Reliable Sealing Performance
Bubble-Tight Shutoff: EPDM, NBR, or Viton seats ensure zero leakage per EN 12266-1 Class A standards
Temperature Flexibility: Suitable for applications from -20°C to 120°C depending on seat material
Chemical Compatibility: Multiple seat options available for different media requirements
4. 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
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
