Cold-wall slide valves in refinery units
Thread Content
I wonder if anyone here has come across cold-wall slide valves (used in FCC) in actual work? Could you recommend some well-known foreign manufacturers that produce such valves (other than Remosa from Italy)?
Remosa was acquired by the British IMI Group; its electro-hydraulic actuators were developed in-house. Regarding the valves used in the FCCU units within UOP’s process packages, in addition to Remosa, there is also Kubota valves from Japan; its electro-hydraulic actuators are of the Egile type manufactured by Mea in the United States. These valves are also used at Sinopec’s Qilu, Zhenhai, and Luoyang refineries, as well as at CNPC’s Lanzhou refinery. I can’t remember the other supplier.
