ASME B16.10 Globe Valves
What ASME B16.10 requires for globe valves — applicability, key and testing requirements, the alternative standards, and compliant supply with full certification.
What does ASME B16.10 require for globe valves?
ASME B16.10 (Face-to-Face and End-to-End Dimensions of Valves, American Society of Mechanical Engineers (ASME)) sets the design, material and testing requirements for globe valves in its scope. ASME B16.10 standardises the face-to-face (FTF) and end-to-end (ETE) dimensions of flanged and butt-welding end valves to ensure interchangeability between valves from different manufacturers. When a replacement valve is specified to B16.10, it can be installed in the same flanged or welded space envelope as the original - critical for plant maintenance and turnaround planning. All major valve types (gate, globe, swing check, ball, butterfly) have specific B16.10 dimension tables.
Applicable Pressure Classes
Key Requirements
- Face-to-face dimensions tabulated per valve type, size, and pressure class
- Tolerances: ±1/16 inch (±1.5 mm) for NPS ≤ 3½; ±1/8 inch (±3 mm) for NPS 4 to 10; ±3/16 inch for NPS 12+
- Short, regular, and long pattern dimensions defined per type
- Rising stem gate valves: face-to-face includes disc travel and bonnet projection
- Butterfly valve face-to-face per Series 13 (lug/wafer) and Series 15 (double-flanged)
- Ball valve FTF per regular and short-pattern designs
Testing Requirements
- Dimensional inspection: face-to-face measurement within B16.10 tolerance
Alternative Standards for Globe Valves
Other standards that also govern globe valves — useful for spec cross-acceptance.
