Application & selection guidance
Choose this identifier when the line is DN125 at PN40 and the body must be 1.0619 cast steel; confirm flange drilling against EN 1092-1 and welding ends against EN 12627, and verify testing to EN 12266-1.
Frequently asked questions
What does the 1.0619 grade mean on this DN125 PN40 bellow globe valve?
1.0619 is the material number of the GS-C25 cast carbon steel the page lists as the body material. The collected page carries both markings for the same execution, so the body certificate should state the grade explicitly; there is no separate alloy content claimed beyond the cast steel designation.
Which standards define this DN125 execution and what are its key figures?
Design is EN 13709 and face-to-face follows EN 558-1, with EN 1092-1 flanges, EN 12627 welding ends and EN 12266-1 testing. In this series the DN125 face-to-face length is 400 mm, Kvs is 264 m3/h (standard plug) or 184 m3/h (throttling plug), and the valve weighs 102.0 kg.
Ordering & documentation
Documents
Ask for the documentation set you need with the inquiry β typical items for this execution (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
A quotation-ready inquiry states: nominal size and pressure rating, body and seat material preference, end connection, operation, and the service medium with temperature. Typical values on this page are benchmark reference ranges; the binding values are confirmed at quotation.
Sample & supply
Supply terms, order quantities and lead time are agreed per order β state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, keep end-face protectors on until installation, and for elastomer- or PTFE-seated executions avoid prolonged outdoor storage β seat compounds age fastest in direct sunlight and freezing conditions.
