U-shape Butterfly Valves with AWWA C504 Standard

Introduction:

1. U-Shaped Disc Design

- Hydrodynamically optimized U-profile reduces head loss by 18-22% versus conventional discs, cutting pumping energy costs in long pipelines.



2. Full AWWA C504 Compliance  

- Certified for Class 150B (175 PSI) operation with ductile iron body (ASTM A536), EPDM seats, and fusion-bonded epoxy coating (FBE) per AWWA C550.  



3. Zero-Maintenance Construction

- Self-lubricating composite bearings and triple-sealed 316L SS stems prevent grit ingress in sandy/gravel environments.  

- OS&Y design for visual position verification.  

4. Buried Service Readiness

- Extended ISO 5211 actuator pads support gear operators or actuators for valve box installations.  

Competitive Differentiation

Energy Savings: U-shape CFD-optimized design reduces pump OPEX by 8-12% annually.  

AWWA-Specific Customization: Modify stem extensions, coating systems (polyurethane optional), or flange drilling (AWWA C207 Class D/E).  

Rapid Deployment: Pre-assembled kits with valve, gear operator, and KIT adapters for buried service.
