ASME B16.10 Valve Face-to-Face Dimensions
This chart gives ASME B16.10 face-to-face dimensions in millimetres for flanged raised-face gate, globe, lift and swing check, and short and long pattern ball valves in Class 150, 300 and 600. Face-to-face length lets a replacement valve drop into the same piping gap.
Teshi Group supplies gate, globe, check and ball valves to API and ASME standards with full test certificates.

Notes
- Face-to-face is measured between the raised faces of the end flanges.
- A dash means no value is listed for that valve type and size.
- Reference values for estimation and checking. Verify against the current edition of the standard and the purchase specification before design, purchase or fabrication.
Reference information compiled from the published standard for convenience. It does not replace the current edition of the governing standard, which takes precedence. Verify critical dimensions and properties before design, purchase or fabrication. Teshi Engineers & Sales Promoters (P) Ltd accepts no liability for errors or omissions.
FAQ
ASME B16.10 Valve Face-to-Face dimensions: common questions
What is valve face-to-face?
The overall length of a flanged valve between its two end flange faces. ASME B16.10 fixes it so valves of the same type, size and class are interchangeable.
Are gate and ball valves the same length?
In Class 150 and 300 a short-pattern ball valve has the same face-to-face as a gate valve of the same size, so they can replace each other.
