Gear Operated U-Shaped Butterfly Valve

Introduction:

1. U-Shaped Disc Design

- Aerodynamic U-profile minimizes pressure drop by 30% compared to traditional butterfly valves, optimizing flow efficiency in high-velocity systems.  

- Enhanced sealing contact with EPDM/FKM seats ensures bubble-tight shutoff.  



2. Heavy-Duty Gear Operator  

- Precision-engineered worm gear mechanism reduces operating torque by 40%, enabling smooth adjustment even under 16-bar (PN16) pressures.  



3. Corrosion-Resistant Construction

- Body: Ductile iron with epoxy coating for corrosion protection in seawater or chemical exposure.  

- Disc: 316L stainless steel U-shaped disc with PTFE-coated bearings for frictionless rotation.

4. Multi-Standard Compliance  

- Meets API 609 (triple offset design principles), ISO 5752 (flange dimensions), and WRAS (potable water approval).
