Triple offset butterfly valve passes FAT for PDH plant

IMI Orton has successfully carried out factory acceptance testing (FAT) on one of its largest ever butterfly valves, which will be used for modulating purposes at a new propane dehydrogenation (PDH) plant in Saudi Arabia.

The metal-to-metal triple offset butterfly valve went through the testing process at IMI Orton’s facility in Piacenza, Italy, to ensure that it met vital performance specifications. The triple offset control valve is an 84″ ANSI Cl. 300, which has been designed to withstand temperatures of up to 730°C. It was delivered to the site in September 2023.

The triple offset butterfly valve, which was built bespoke for this project, is designed to operate at expected temperatures of 690°C, with a maximum design temperature of 730°C, and at tightness levels meeting FCI 70-2 class V. Its stainless steel, non-rubbing seat design also ensures a long service life – a vital consideration for operation in propane dehydrogenation plants.
