TECHNICAL GUIDE

Wafer vs Flanged Butterfly Valves

Connection type affects installation space, alignment, piping support and maintenance strategy.

What matters

Wafer bodies fit between pipeline flanges and use the line bolting to clamp the valve in place. Flanged bodies connect through their own flange holes.

What to confirm

Confirm pipeline flange standard, available face-to-face space, piping loads, isolation philosophy and maintenance access.

Procurement note

Model designations do not replace an operating-condition review. Final selection must follow the actual project requirements and approved technical documents.
