1. Main Specifications
W-type ball valve core
Uses a composite flow channel design with a venturi hole
The linearity of the coefficient of flow (Kv) reaches ±3%
Flow resistance coefficient ξ=2.5 (40% lower than conventional ball valve)
Double Scale Adjustment System
External scale: flow rate (m³/h)
Internal Scale: Open Percentage (%)
Minimum adjustment accuracy of 0.5 m³/h (sheet DN20)
Engineering Level Interlock Design
Patented anti-rotation buckle design
A special wrench (compliant with BS EN 1254) is required for adjustment
2. Advantages of engineering application
