Triple offset butterfly valve
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 . 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 . “ Working closely with our customer to demonstrate the potential of triple offset butterfly valves for use in high-stress conditions has been a very rewarding experience ,” explains Giacomo Boledi , Area Sales Manager at IMI Orton . “ Of course , a key part of this exciting project is ensuring that any newly designed component can meet the application requirements , so we ’ re thrilled that this new valve has passed our rigorous FAT process .” “ Other valve types have traditionally been used in these scenarios , but with facility performance under increasing scrutiny and the need to reduce OpEx costs , it is encouraging to see new approaches being explored . The fact that the valve is required to continuously move for such a demanding , precise application means its tightness , compactness and robust full metal construction is vital to this application , so testing was especially important in this case .”
