IMI Z&J

IMI Z&J provides high performance isolation valves for the refining, petrochemical and metals industries, with operations including its Duren and Houston facilities. Expert engineers and advanced manufacturing methods enable tailored technologies that meet the toughest temperature and cycling demands in downstream processing.

Applications include fluidised catalytic cracking, where robust flow control and isolation technologies serve high-temperature, high-pressure and catalyst-rich environments; coking, where reliable isolation for delayed coking units reduces unplanned downtime; and ethylene production, supported by transfer line isolation, bypass and steam generation valves. Further coverage extends from dehydrogenation units to IsoSiv and TIP systems. For metals operations, IMI Z&J blast furnace valves survive intense heat, pressure and abrasive conditions, helping maintain stable flow and protect critical equipment.
