Emerson’s Top-Entry Cryo Valve Limits Leakage and Energy Loss

The Fisher IC2 Cryogenic Top-Entry Control Valve, ideal for cold box applications in air separation units, hydrogen liquefaction and LNG production. The IC2 control valve meets the stringent demands of these extremely low-temperature environments, operating reliably 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, meeting or surpassing U.S. Environmental Protection Agency standards.

The Fisher IC2 control valve offers hardened trim materials, Enviro-Seal packing and metal-to-metal seating, and the top-entry makes maintenance easier and includes 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 IC2 control valve is rated for the CL600 pressure class, and currently available from 1 to 4 inches (DN25 to DN100).
