Aug 01 2025The Ultimate Butterfly Valve Dimensions Archive
This resource is designed as a definitive digital archive for engineers and standards professionals. It contains exhaustive dimensional data for butterfly valves, compiled directly from major global standards. Our goal is completeness and precision, providing the data as specified in the documents, including full size ranges and regional standards often omitted elsewhere.

Standard Systems: A Deep Dive
Before presenting the master data table, it is crucial for the researcher to understand the context and interplay of the key regional standards included in this archive.
Australian Standards (AS)
Primarily governed by AS 4795.1 for butterfly valves and AS 2129 for flanges. AS 2129 specifies flange dimensions by "Table" (e.g., Table D, Table E), which are vital for any project in Australia. While there is some similarity to ISO/EN standards, they are not directly interchangeable.
View AS DataGOST (ГОСТ) Standards
GOST refers to the technical standards for the CIS region. For valves, ГОСТ 13547 defines face-to-face dimensions. Dimensions are often unique and must be strictly adhered to for projects in this region. ПН (PN) denotes the nominal pressure.
View GOST DataChinese Standards (HG/T)
HG/T standards are specific to the chemical sector in China. HG/T 3704 provides dimensions for wafer butterfly valves. These standards often show strong influence from international standards but can have critical differences. Consulting HG/T is non-negotiable for chemical projects in China.

Dimensions listed are as specified in the respective standards for short pattern valves (typically concentric resilient-seated). A hyphen (-) indicates the standard does not specify a value for that size.

Archivist's Note:
Standards Define the Interface.
Manufacturers Define the Product.
These standards are a contract for interchangeability. They guarantee that a compliant valve will physically fit a compliant flange and pipe section. They govern connection points like Face-to-Face and drilling patterns.
They do NOT dictate internal design. Wall thickness, shaft diameter, disc profile, and operator size are manufacturer-specific variables determined by performance requirements. Therefore, these charts are for authoritative design reference, but final fabrication must always be confirmed against the certified drawing from the specific manufacturer.
