在70年代末期，oliver公司前身主要是生产针阀，英国奥利弗oliver止回阀oliver球阀上海代表处，标准均采用NACE MR-01-75标准，我们的针阀及其针阀阀组广泛应用于天然气和石油行业。
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.
