The specified range is DN 100 to DN 400 at pressure class DP100, with telescopic functional extensions and actuation. The valves must use all-metal seals and tungsten-carbide coating on the ball and seat rings, at a minimum thickness of 250 micrometres. The notice cites DVGW G 463, DIN 3230-5 test group 3 and DIN EN 14141; hydrogen applications must also meet DVGW G 406. No deadline, estimated value or qualification application details are stated in the available source. - Status: open - Country: DE - Buyer: EWE NETZ GmbH - Submission deadline: Not available (unavailable) - Original notice: https://oeffentlichevergabe.de/ui/de/notices/1ac4f56b-fc49-4d11-b970-129b6b779ae6 - Source checked: 2026-10-13T12:56:16.992790Z ## Source-backed public facts ```json { "id": "b3917e01-db79-4b1a-a03b-6ed589de2b26", "revision": 1, "modifiedAt": "2026-10-13T13:10:46.013262+00:00", "sourceCheckedAt": "2026-10-13T12:56:16.992790Z", "stale": false, "url": "https://zephior.com/tenders/b3917e01-db79-4b1a-a03b-6ed589de2b26/qualification-system-dp100-ball-valves-gas-transport", "locale": "en", "title": "Qualification system for DP100 ball valves in gas transport pipelines", "summary": "EWE NETZ GmbH is establishing or operating a qualification system for fully welded ball valves for underground gas transport pipelines.
