The end of the transitional period is approaching! Introducing ball valves that use materials compliant with the positive list system.

The transitional measures for the positive list will end at the end of May 2025, so those who are not prepared need to take urgent action. This positive list system applies to synthetic resins. Ball valves are no exception, and if you are using resin valves or resin materials in ball seats, action is required. Our oil-free ball valves use materials that comply with the positive list system. We produce a substantial quantity and have them in stock, so they are readily available. Additionally, since they are produced domestically, we have solid traceability and can accommodate a wide range of document issuance requests. Various documents can be issued according to your needs. ● Main documents that can be issued: - Oil-free treatment certificate - Product inspection report - Material certificate (mill sheet) *Can be provided for each part upon request. - Non-applicability certificate (item-by-item comparison table) - RoHS directive substance non-containment certificate We will also respond to document issuance requests based on other requirements.
