Emerson has introduced the Fisher IC2 Cryogenic Top-Entry Control Valve, designed for cold box applications in air separation units, hydrogen liquefaction and LNG production. The IC2 control valve aims to meet the demands of extremely low-temperature environments, operating at temperatures as low as -452 degrees Fahrenheit (-269 degrees Celsius). The IC2 control valve includes cryogenic enhancements, including a narrow extension diameter and fluid baffle. These components work together to minimize heat conduction, reducing the energy required to maintain process fluid temperatures, while enhancing overall operational sustainability. The IC2 control valve’s Fisher enhanced ENVIRO-SEAL packing system and bellows limit leakage to a maximum of 100 parts per million by volume.

The Fisher IC2 control valve features hardened trim materials, enhanced ENVIRO-SEAL packing and metal-to-metal seating. When maintenance is necessary, the IC2 valve offers simple serviceability via features such as top-entry, a single packing nut, a modular stem assembly, an independently replaceable bellows, and a replaceable valve plug and seat ring, with a special tool provided for seat ring removal. The control valve is rated for the CL600 pressure class, and is available in line sizes from 1 to 4 inches (DN25 to DN100), with more options forthcoming.
