About Us

Oliver Twinsafe Ltd offers an established range of Double Block and Bleed (DBB) large bore pipeline valves engineered to minimise space and weight, effectively reduce potential leak paths and reduce maintenance requirements on both new and existing pipelines. These valves offer a single pipeline valve solution for companies operating in the Oil, Gas and Petrochemical industries worldwide. From 1” to 18” ball sizes, soft seated and metal seated to leak rate A and to API / ASME standards.

Reliability Under Pressure

As oil and gas become increasingly difficult to extract, engineers at Oliver Twinsafe Valves Ltd are faced with ever-changing criteria in the design and manufacture of their pipeline valves products to satisfy service in some of the most extreme environments known to man.

Design engineers at Oliver Twinsafe work closely with our clients to provide bespoke flow control solutions. We are continually expanding our range of valves for clean and renewable resources such as Carbon capture, Hydrogen and LNG-specific valves.

Engineering Through Innovation

Recognised worldwide for superior quality and precision engineering, Oliver Twinsafe Ltd are renowned for reliability and consistent performance. With a wide global presence, our offices are located in all major oil and gas countries. We continuously work with existing and new clients to develop custom valve solutions of all sizes.
Our companies adopt a technical project approach, where necessary, to ensure that we can develop valves that adhere to the strictest quality and safety guidelines while fitting into our client’s existing project plans. To date, Oliver Twinsafe Ltd has worked alongside some of the largest international Oil, Gas and Petrochemical projects in the world.

Staff Testimonials

About Us

Richard Ware, Goods-in Inspector, Oliver Valves

I joined Oliver Valves on 14th April 2005. In the first few months, I started on needle valves on the shop floor and then moved into the goods receipt area within a year. I check all parts received as well as checking certification. 

During the last 16 years, I have become responsible for PMI (positive material identification), raw material stores, cycle counts, liquid and general waste and assist with customers/QA audits.  In my role at Oliver Valves, I work with many departments which include Sales, Purchasing, Engineering, Documentation and Distribution.
“Every day is different and I enjoy working at Oliver’s. I look forward to the future and new challenges with great support from my colleagues.”

About Us

Paul Headen, Supply Manager, Oliver Valvetek

Paul joined the business originally in 2008 as a project manager and became a key player in the growth of Oliver Twinsafe Valves as Supply Manager. His career took him elsewhere in 2015 but he returned in 2019 to take the helm in Oliver Valvetek as Supply Manager where he continues to develop and grow the business.

“Working for a company that allows me to operate with autonomy enabling me to develop my knowledge and interpersonal skills within my role. As part of a family-run business, you feel the full support of everyone in the business. If needs must, everyone from the owner down will get involved to find solutions and progress issues to a positive conclusion. The business itself is a great model for other businesses to follow who wish to be seen as the best of British.”

About Us

Steve Williams, Key Accounts Manager, Oliver Valvetek

Steve Williams joined the Oliver Family of companies in 1991.  Steve’s background in Aerospace Engineering attracted him to join the Oliver family and over the past 30 years has held roles in Research & Development, Project Sales, Quality Manager for the 3 companies, General Manager for Valvetek and currently, over the last 5 years, as Oliver Valvetek Subsea Key Account Management.

Steve previously implemented the companies Quality Management and Quality Control ISO9001 systems to accommodate for the different business product and customer requirements. This made the three businesses world and market leading in supplying Quality and reliable valve products. He has also previously worked on overseas sourcing initiatives, including working on Supply chain Quality control and Assurance development in India and Italy. 

Steve’s current role as Key Account Manager is allowing him to work with all the major Subsea production companies and end users on valve standardisation programs and process/product rationalisation. His knowledge both technically and commercially, alongside his experience in Quality Management, is changing customers approaches to business partnerships, product design and importantly removing inherent non-value-added costs.

“If someone had asked me 30 years ago, what would I be doing now I seriously would not have predicted my career progression. We say that Oliver is a Family and it is just that in every sense of the word. What gets me out of bed every day? Every day I learn something new, technologies are always advancing, customer partnerships constantly evolve and to be the best of the best, you have to be always at the top of your Industry. Oliver’s is just that.”

About Us

Alex Green, Production Operative, Oliver Twinsafe Valves

Alex joined Oliver Twinsafe four years ago with no previous experience in the industry or in engineering. Through hard work, enthusiasm, and applying himself thoroughly to tasks given to him his potential was noticed by our Chairman, Michael Oliver, who offered him the opportunity to take an Engineering apprenticeship sponsored by the Company. Three years later Alex has successfully completed his apprenticeship and is very keen to build on this to allow him to progress within the business.

During his time at Oliver Twinsafe, Alex has worked in the goods-in department, stores and stock control, non-destructive testing, and more recently on valve production.

“I really appreciate the opportunity and support given to me by Oliver’s and the people working around me. Having spent time in various departments, my understanding and knowledge of the workings of the business continues to increase, and I look forward to progressing, by learning new skills and developing my role further.”


Quality Standards & Certificates

We are extremely proud of our product and level of customer service and together with our ISO 9001:2015 quality management system, our state-of-the-art computerised ERP and ARP systems and our highly trained and passionate workforce; we consistently achieve industry-leading HS&E, quality and delivery performance, which is often at 100%.

By forming strong relationships built on trust and respect for all our highly valued and respected team members, customers and suppliers, we seek continual feedback to strive for continual improvement. It is not unusual for us to enter into Supply Agreements and Strategic Stocking Programmes for mutual benefit, which increases product quality while reducing costs and lead times.

We are highly experienced with pre-production meetings and project management and actively encourage customer engagement. This has resulted in several industry-respected awards, the most recent being a Supplier Partnership Award with a leading subsea tree and manifold manufacturer in recognition of our innovation, standardisation and excellence in class.

With a large number of Oliver facilities and personnel strategically located throughout the globe, you can be assured of a truly professional and highly personal level of customer service.

By contacting us at the early stages of a project, we can draw on our vast experience and bring technical and commercial know-how into the equation.

In many instances, this has saved the contractor or end-user practical design and construction time, leading to obtaining oil or gas much sooner and achieving a far quicker return on their investment.

During August 2020, Oliver Valves Ltd, Oliver Valvetek Ltd, Oliver Twinsafe Valves Ltd all underwent ISO 9001:2015 recertification audits and were recommended for continued approval by our certification body (Lloyd’s Register).

In addition to the ISO certification, Oliver Valves has also achieved approval for the American Petroleum Institute (API) Q1 Quality Management System as well as API 6A product specification.
