Unleashing excellence in Ethylene production
At IMI Critical Engineering, we are the leading supplier of specialist severe service valves for the entire ethylene production process. Ethylene, a key building block in a wide range of everyday goods, including plastics, solvents, paints, textiles, medicines, and cosmetics, is produced through thermal cracking at extremely high temperatures and pressures. Our state-of-the-art technology, exemplified by the IMI Z&J double disc through conduit (DDTC) type gate valve design, ensures optimal performance and efficiency in this specific application.

Unparalleled valve solutions
Our comprehensive product portfolio includes not only furnace isolation valves like transfer line valves (TLV) and decoking valves (DV), but also control, bypass, anti-surge, steam control, and isolation valves tailored to the unique needs of the ethylene industry. With a global footprint, we have already installed over 2,000 valves in ethylene plants worldwide, solidifying our position as the trusted provider in this industry.
