Struggling with valve installation costs and durability in your industrial pipelines? Our detailed comparison of wafer type vs lug type butterfly valves helps purchasing managers and technical directors make data-driven decisions that maximize ROI and operational reliability.
These pain points directly impact your supply chain continuity and operational costs. Understanding the differences between wafer and lug type butterfly valves is essential to solving these issues.
| Specification | Wafer Type | Lug Type |
|---|---|---|
| Connection Type | Sandwiched between flanges, no through-bolts | Bolted to one flange side, through-bolts for pipeline isolation |
| Pressure Rating | Up to PN16 (150 psi) | Up to PN25 (250 psi) or higher |
| Installation Complexity | Lower - fewer bolts | Moderate - more bolts, requires flange alignment |
| Maintenance | Requires pipeline shutdown on both sides | Can isolate pipeline section for maintenance |
| Typical Applications | Water treatment, HVAC, light industrial | Chemical, oil & gas, heavy industrial |
| Material Options | Cast iron, ductile iron, stainless steel | Cast iron, ductile iron, stainless steel, carbon steel |
Wafer valves are installed between two flanges and require flange bolts on both sides. Lug valves have threaded lugs allowing installation on one flange side and enable pipeline isolation.
