Wafer-Type Butterfly Valve Technical Specifications
Structure & Operating Principle
Axially symmetric disc design, precisely mounted along pipeline diameter
0°-90° rotation adjustment, achieving full flow at 90° open position with minimal pressure drop
Cylindrical valve body ensures stable fluid dynamics
Key Advantages
✓ Compact design: 40% lighter than flange-type valves with space-saving installation
✓ Rapid actuation: Quarter-turn operation (manual/pneumatic/electric actuators available)
✓ Precision casting: Surface roughness Ra≤3.2μm, 100% X-ray inspected for defect-free construction
Industrial Applications
✓Coal chemical: Gas scrubbing system diverter valves
✓Petrochemical: Product pipeline flow control
✓Pharmaceutical: GMP-compliant sterile process lines
✓Special services: PTFE-lined/316L options for corrosive media
