(4 lug style butterfly valve)
The 4 lug style butterfly valve
features a compact, high-torque design optimized for systems requiring ≤150 PSI pressure handling. Unlike wafer-style valves, its dual-lug configuration enables direct pipeline mounting without additional flange kits, reducing installation costs by 18-22% according to 2023 ASME benchmarks. Industries from chemical processing to HVAC increasingly favor this model for its 92-95% flow efficiency in DN80-DN600 sizes.
Rigorous testing under ASTM F1370 standards reveals superior performance metrics:
These specifications make 4 lug valves ideal for steam distribution (18% adoption increase since 2021) and aggressive media handling.
Advanced features distinguish premium 4 lug models:
Feature | Standard Valve | Enhanced 4 Lug |
---|---|---|
Body Material | CF8M Stainless | Duplex 2205 |
Seal Life | 5-7 years | 12+ years |
Actuation Time | 8-10 seconds | 4.2 seconds |
Top installation suppliers demonstrate key differentiation:
Supplier | Lead Time | Certifications | Price Premium |
---|---|---|---|
Factory A | 6 weeks | API 609, ISO 15848 | +22% |
Factory B | 9 weeks | ASME B16.34 | +15% |
