Features & Benefits
With several years of experience in high pressure ball valves for offshore platforms and FPSO, Velan ABV has developed a new generation of compact valves in both a single and double ball configuration. Our design provides a competitive solution in an ever-expanding market that faces technical and economic challenges. We offer a wide range of two or three-piece forged bolted body trunnion mounted ball valves. Two independent seats provide easy bidirectional sealing to ensure the greatest level of tightness and reliability under high pressure and temperature conditions in critical isolation services. High pressure compact ball valves have the same reliability and level of quality as traditional API valves but with significant space and weight savings due to the compact flange design integrated into the valve closures. Compact welding neck flanges that connect the pipeline to the valve provide further space savings. Design and selection of materials are fully customizable to meet the customer’s project specifications.
