ISO 5752 is the international standard that specifies face-to-face (F2F) and center-to-face (C2F) dimensions for metallic industrial valves. Standardized dimensions allow valves from different manufacturers to be installed or replaced without modifying the piping system.
What is ISO 5752?
ISO 5752 defines installation dimensions for metallic valves with flanged or wafer-type end connections. These standardized dimensions ensure interchangeability and simplify maintenance, engineering design and equipment replacement.
The standard is widely used throughout the process industries to ensure compatibility between valves supplied by different manufacturers.
What are Face-to-Face Dimensions?
Face-to-face (F2F) dimensions represent the distance between the two end connection faces of a straight-through valve installed in a pipeline.
Center-to-face (C2F) dimensions apply mainly to angle-pattern valves and define the distance from the centerline of one connection to the face of the other connection.

Frequently Asked Questions
What does ISO 5752 specify?
It specifies standardized face-to-face and center-to-face dimensions for metallic industrial valves.
Does ISO 5752 apply only to flanged valves?
No. It also includes wafer valves and other metallic valve designs using standardized installation dimensions.
What is the difference between ISO 5752 and EN 558?
ISO 5752 is an international standard, while EN 558 is the corresponding European standard. Many dimension series are technically equivalent.
Conclusion
ISO 5752 is one of the most important international standards for industrial valve installation dimensions. By standardizing face-to-face and center-to-face dimensions, it enables valve interchangeability, simplifies maintenance and reduces installation costs across industrial facilities.
