Oliver Twinsafes' established range of Double Block and Bleed (DBB) large bore pipeline ball valves will save you space and weight, reduce potential leak paths and minimise maintenance requirements on both new and existing pipelines. 英國(guó)奧利弗oliver止回閥oliver球閥上海代表處，Oliver Twinsafe offer a range of valves from 1" to 16" in either full or reduced bore sizes, in ASME pressure Classes from 150 to 2500 and API ratings up to 10,000 API. Both soft and metal seated options are available.

在70年代末期，oliver公司前身主要是生產(chǎn)針閥，英國(guó)奧利弗oliver止回閥oliver球閥上海代表處，標(biāo)準(zhǔn)均采用NACE MR-01-75標(biāo)準(zhǔn)，我們的針閥及其針閥閥組廣泛應(yīng)用于天然氣和石油行業(yè)。

These valves are designed to offer a single valve solution, which in most cases will fit in the same space as a single ball valve to ASME B16.10 overall length, but giving true double isolation for maximum safety and reducing process problems due to valve leakage. The compact design saves weight, space and reduces costly installation charges.

大部分應(yīng)用于石油，天然氣和石化行業(yè)。而Oliver Valvetek閥門主要用于深水海洋作業(yè)領(lǐng)域。Oliver Twinsafe球閥，針閥等閥門則是應(yīng)用于大型的石油或者天然氣管道。

All valves are designed and tested within the requirements of API 6D, ASME B16.34, API 598 and ASME VIII. Material certification to BS EN 10204 3.1 or 3.2 and unique serial numbering system ensures full traceability on all our valves.
