صمام التحكم العلوي للتبريد العميق Fisher IC2 | مورد Fisher

المزايا التقنية الحاسمة

• Top Entry Design: The trim is fully extractable through the extension. This critical feature allows for maintenance and part replacement while the valve body remains enclosed within an insulated cold box structure, significantly reducing downtime and insulation disturbance.

• High Performance Thermal Features: To protect the packing and actuator, the IC2 utilizes a tight-fit fluid baffle that prevents the circulation of cryogenic liquid into the bonnet extension. An optional displacer is available to further insulate the extension, keeping the upper components at ambient temperature.

• Cryogenic-Specific Construction: The valve body and extension are manufactured from stainless steel specifically rated for low-temperature toughness. The design accounts for material contraction and thermal gradients to maintain mechanical integrity at cryogenic levels.

• Rugged Metal-to-Metal Seat: Unlike soft-seated valves that may fail as materials harden in the cold, the IC2 features a precision-manufactured metal seat. This design provides repeatable, reliable shutoff at both ambient and cryogenic temperatures, reducing long-term maintenance costs.

• ENVIRO-SEAL Fugitive Emission Protection: Equipped with the enhanced ENVIRO-SEAL live-loaded packing system, the IC2 ensures a superior stem seal. This is vital for preventing the loss of expensive process fluids (like Helium or Hydrogen) and maintaining environmental compliance even under extreme thermal cycling.

• Ease of Service: The valve features a modular stem assembly and a single, easy-to-adjust packing nut. Components like bellows, plugs, and seat rings are interchangeable and can be replaced independently of the rest of the trim.
