CBF02-TU03--Operation and Maintenance Manual DOWMLOAD

Key Features:

1. U-Shaped Disc Hydrodynamics

• Optimized Flow Path: Advanced computational fluid dynamics (CFD) design reduces pressure drop by 25-30% compared to conventional disc configurations  

• Energy Efficiency: Lower flow resistance translates to substantial pumping energy savings in continuous operation systems  

• Cavitation Control: Streamlined disc profile minimizes turbulent zones, extending valve and pipeline service life  



2. Ductile Iron Robustness

• Material Excellence: EN-GJS-500-7 ductile iron provides superior mechanical strength and impact resistance  

• Corrosion Protection: Standard 250μm epoxy coating with optional 300-400μm thickness for aggressive environments  

• Structural Integrity: Reinforced body design withstands water hammer and pressure surges up to PN16 rating  



3.Premium Sealing Performance

• Bubble-Tight Shutoff: EPDM/NBR/PTFE seat options ensure zero leakage compliance with EN 12266-1 Class A standards  

• Temperature Adaptability: Reliable performance across -20°C to 120°C operational range  

• Long Service Life: Resilient seating materials maintain integrity through 50,000+ operating cycles  

4. Operational Excellence

• Low Torque Operation: Double offset design reduces operating torque by 35% for smooth manual or actuated control  

• Maintenance-Free Design: Self-lubricating bearings and corrosion-resistant components eliminate routine maintenance  

• Versatile Actuation: ISO 5211 mounting pad compatible with manual levers, gear operators, or pneumatic/electric actuators
