RAYS large-sized & high-pressure butterfly valves have delivered to PETRONAS project


Recently, RAYS have successfully completed 4 pcs 36” 600LB large sized high pressure. Butterfly valves which strictly follow ITP procedures for production and testing which have passed various tests required by the customer from PETRONAS Malaysia for DGDM Pipeline valve replacement at MLNG Bintulu.



This project is for a customer’s maintenance project which deals with replacing the original butterfly valve made in Europe where only a few valve factories can produce such big valves. Through a series of solutions such as: advanced 3D design, finite element analysis, 3D coordinate and detection in the process of processing control – RAYS brings great confidence to the customer and encourages the customer to give the project to us.
