Emerson’s new cryogenic valve limits leakage and energy loss

Emerson has introduced the Fisher™ IC2 Cryogenic Top-Entry Control Valve, ideal for cold box applications in hydrogen liquefaction and LNG production.
Cold boxes are insulated enclosures that house cryogenic equipment, such as heat exchangers, distillation columns, piping and valves.
The IC2 control valve meets the stringent demands of these extremely low-temperature environments, operating reliably at temperatures as low as -269 degrees Celsius.
Operating in cryogenic environments can be challenging due to various factors, including product and energy losses due to emissions, which lead to reduced profitability, high maintenance costs and regulatory concerns.
To address these and other issues, the IC2 control valve includes high-performance cryogenic enhancements, including a narrow extension diameter and fluid baffle.
These components work together to minimize heat conduction, thereby reducing the energy required to maintain process fluid temperatures, while enhancing overall operational sustainability.
The Fisher IC2 control valve provides longevity with its 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.
