Marshalltown, Iowa (April 8, 2026) - Emerson has launched the Fisher™ IC2 low-temperature direct-acting control valve, which is highly suitable for applications in air separation units, hydrogen liquefaction, and LNG production involving cold boxes. A cold box is an insulated enclosure structure that houses heat exchangers, distillation towers, pipelines, and valves and other low-temperature equipment. The IC2 control valve can meet the stringent requirements of its ultra-low temperature environment and still operate reliably at the lowest -269 degrees Celsius (-452 degrees Fahrenheit) conditions. 

Operating in low-temperature environments often poses numerous challenges, such as product leakage and energy loss due to convection, which subsequently lead to decreased profits, increased maintenance costs, and heightened regulatory pressure. To address these and other issues, the IC2 regulating valve adopts a number of high-performance low-temperature optimization designs, including reducing the diameter of the extended part and installing guide plates, among other structures. 

These components work together to significantly reduce heat conduction, thereby reducing the energy consumption required to maintain the fluid temperature during the process, and at the same time enhancing the overall operational sustainability. The IC2 control valve is equipped with Fisher's enhanced ENVIRO-SEAL™ packing system and bellows, which limits the leakage to less than 100 parts per million per volume, meeting and even exceeding the relevant standards of the US Environmental Protection Agency. 

The Fisher IC2 control valve is equipped with hardened valve internals, enhanced ENVIRO-SEAL™ packing, and a metal-to-metal sealing structure, featuring excellent durability. The IC2 valve achieves convenient maintenance through multiple designs, including a push-in structure, a single packing nut, a modular valve stem assembly, a replaceable bellows, and replaceable valve core and valve seat rings, and is equipped with a dedicated tool for easily removing the valve seat ring. 

The pressure rating of the IC2 control valve ranges from CL600 and offers 1 to 4 inches (DN25 to DN100) diameter specifications. More configuration options will be introduced in the future.
