Wafer-Type Butterfly Valve Technical Specifications
EPDM PTFE PFA Durable Ductile Iron Control Wafer Butterfly Valve for Industry
Structure & Operating Principle
Showcasing an axially symmetric disc design,meticulously mounted along the pipeline diameter,
allowing a seamless 0°-90° rotation adjustment,resulting in full flow at a 90° open position with minimal pressure drop.
The cylindrical valve body is engineered to ensure stable fluid dynamics.
Key Advantages
✓ Compact and efficient design: Remarkably 40% lighter than traditional flange-type valves, offering space-saving installation.
✓ Swift and reliable actuation: Featuring a user-friendly quarter-turn operation with optional manual, pneumatic, or electric actuators.
✓ Precision casting excellence: Surface roughness is Ra≤3.2μm, with 100% X-ray inspection ensuring a defect-free construction.
Industrial Applications
✓Coal chemical: Optimal for gas scrubbing system diverter valves.
✓Petrochemical: Ideal for precise product pipeline flow control.
✓Pharmaceutical: Designed for GMP-compliant sterile process lines.
✓Special services: PTFE-lined/316L options available for handling corrosive media.
Performance Parameters
• Size range: Accommodates DN50-DN2000 (2"-80"), offering versatile sizing options.
• Pressure rating: PN10-PN40 (ANSI 150LB-300LB), ensuring robust performance under pressure.
• Leakage class: ISO 5208 Grade A, guaranteeing superior sealing and minimal leakage.
• Temperature range: From -29°C up to 200°C, extendable to an impressive 450°C for special configurations.
