Oliver Twinsafe Valves has just finished producing the largest valve in its history.

The product has been specified for a project based off the coast of Louisiana in the Gulf of Mexico.
A 12-inch 1,500-pound double block and bleed valve was specifically produced to cater for the high-pressure levels within the pipelines on the project.
“Constructed in accordance with ASME B16.34, the carbon steel valve weighs a total of 4.6 tonnes and utilises double block and bleed trunnion- mounted ball valves to offer the ultimate in performance and safety,” Oliver Twinsafe said.
“The project utilised six of the 12-inch valves as part of an integrated package of valves from Oliver Twinsafe Valves, which saw a significant number of double block and bleed ball valves in sizes from 1 inch up to 12 inches being installed throughout the project on main pipelines for process isolation.
“Oliver Twinsafe Valves was selected for its ability to supply its proven double block and bleed valves in the larger 12-inch full bore size. In addition, the local and global technical support the team can offer throughout the process, from the initial query through to the installation, was key in the decision-making.”
Commenting on the project, Mark Oliver, deputy chairman at Oliver Twinsafe Valves, said: “This project required a vast amount of double block and bleed ball valves that could safely operate process isolation applications to the highest standard and we could provide the valves in a wide range of sizes to meet the specific needs.”
Oliver Twinsafe Valves utilises trunnion ball technology to offer increased safety measures within one valve body, minimising the risk of leaks whilst offering significant weight and space savings over two standard isolation ball valves (in typical double block and bleed format).  
Formed in 2000, Oliver Twinsafe Valves developed a unique groundbreaking technology which provides single bodied double block and bleed pipeline ball valves up to 16-inch bore size and many to B16.10 standard length and full bore to offer the ultimate in safety. Utilising proven trunnion ball technology in a patented package, Oliver Twinsafe Valves provides customers with reduced space, weight and cost savings within the worldwide oil, gas, petrochemical, LNG and mining industries.
