On August 23, 2024, under the witness of representatives: from SGS, the National Valve Quality Supervision and Inspection Center (Zhejiang), and the project owner – a batch of large-diameter high-pressure 40″-900Lb metal seated zero leakage ball valves from RAYS exceeded expectations by passing multiple Factory Acceptance Tests (FAT). This includes: hydraulic pressure performance tests, low-pressure air tests, stem packing fugitive emission tests, and torque tests.
During the tests, this batch of products achieved leakage rating A and met the low torque requirements under full differential pressure, receiving unanimous recognition from both the owner and third-party authoritative organizations.
In early 2024, after RAYS won this highly challenging project, our R&D center and manufacturing team collaborated successfully and recently delivered it.
Unlike traditional soft-seated structures, this trunnion mounted ball valve employs a: multi-layer metal seat and packing design, pressure-induced elastic deformation of the ball seat based on element analysis, and enhancing seating reliability. This design allows the product to perform well in complex conditions involving natural gas with particulate matter & heavy condensate oil, while also meeting ISO15848-1 fugitive emission ECO- friendly requirement.
The low torque design enables the use of smaller actuators. Under measured full pressure differentials, the torque is over 30% below the average level. This allows for easy opening and closing, effectively reducing the procurement costs of actuators and further satisfying users’ pursuit of high cost-performance products. After thorough technical disclosure and program validation in the preliminary phase, three valves from this batch were successfully assembled and pressure tested in one go!
Once delivered, this project will be used in one of the world’s largest natural gas and condensate oil extraction projects. RAYS, as a Chinese manufacturer, has delivered the first batch of 40″-900Lb specification metal-seat, high-pressure, zero-leak trunnion mounted ball valves, marking a significant technological breakthrough and a major milestone in RAYS’ growth trajectory!
Inspire infinite possibilities.
Let’s meet in the future!
