Emerson has introduced the Fisher IC2 cryogenic top-entry control valve for cold box applications in air separation units, hydrogen liquefaction and LNG production. Cold boxes are insulated enclosures that contain cryogenic equipment such as heat exchangers, distillation columns, piping and valves. The IC2 valve is designed for operation at temperatures down to -452 F (-269 C).
The valve includes a narrow extension diameter and fluid baffle to reduce heat conduction and help maintain process fluid temperatures. Its ENVIRO-SEAL packing system and bellows limit leakage to a maximum of 100 parts per million by volume, in line with U.S. Environmental Protection Agency standards.
The valve also uses hardened trim materials, Enviro-Seal packing and metal-to-metal seating. Maintenance features include top-entry access, a single packing nut, a modular stem assembly, an independently replaceable bellows, and replaceable valve plug and seat ring components. A tool for seat ring removal is included.
