Oliver Twinsafe Pipeline Valves

Oliver Twinsafe has been around for over 40 years, and manufactures precision quality Pipeline valves well equipped to deliver true reliability and performance under the most strenuous of environments.

Oliver’s established range of Double Block & Bleed (DBB) large bore pipeline valves save space and weight, reduce potential leak paths and minimise maintenance requirements on both new and existing pipelines. 

Oliver Twinsafe offers 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. 

Rigorous In-House Testing Facilites

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 a unique serial numbering system, ensure full traceability for all of their valves.

Oliver has custom state of the art test stations which allow larger valves to be tested easily, accurately and quickly on water, air and gas media.

They also perform fugitive emission testing to ISO 15848 and firesafe testing to ensure all valves are certified to API 607, API 6A and ISO 10497, and facilities for low and high temperature testing to meet customer requirements.
