Design institutes and project engineers use this page to compare the three flange standards supported across the RUNKE PN10 valve range, and to request product datasheets. All data below is taken from the official RUNKE catalogue.
| Standard | Full Name | Pressure Rating | Main Export Markets |
|---|---|---|---|
| DIN | DIN EN 1092-1, PN10 flange drilling | PN10 (10 bar @ 20 °C) | Europe, Middle East, Australia |
| ANSI | ASME B16.1, Class 125 | PN10 equivalent working pressure | North America, South America |
| JIS | JIS B2210, 10K | 10K (≈ PN10 working pressure) | Southeast Asia, Japan, Korea |
| Valve series | Pressure rating by size (official) |
|---|---|
| Lever & gear butterfly valve | PN10 (2"–8") · PN6 (10"–12") · PN4 (14"–16") |
| Non-actuator (ISO 5211) butterfly | PN8 (2"–6") · PN6 (8") · PN5 (10"–12") · PN4 (14"–16") |
| True-union ball valve | PN16 (1/2"–2") · PN10 (2-1/2"–4") |
| Check / foot valve series | PN10 (up to 6") · PN6 (8" and above, wafer series) |
| Size | Body Ø D (mm) | DIN / GB | ANSI Class 125 | JIS 10K | |||

Source: RUNKE official catalogue (butterfly valve series). PCD = pitch circle diameter; n-Øe = number of holes × hole diameter. Ball valves and socket-end valves use socket standards (DIN / ANSI / JIS / BS) instead of flanges — ask us for the socket-dimension table.
⚠ Data from the official catalogue — still verify against the approved drawing before fabrication or ordering.
Click a product name to open its page, or Request → for the PDF datasheet (dimensions per standard, material list, torque data). We send it within 24 working hours (GMT+8).
Approved duty: clean water service at PN10 (10 bar @ 20 °C). The rating changes with size — check the table in section 2.1 before selecting.
