Application
The SK Advantage Series of Stainless Steel Globe Valves are designed for handling cryogenic liquids through trailer, bulk vessels and piping configurations. Ideal service medium includes Oxygen, Nitrogen, Krypton, Carbon Dioxide, Dinitrogen Monoxide, Carbon Dioxide, Methane, Ethane, Ethylene, Argon and LNG . Our Kold-Seal stem seal technology assures a tight seal preventing cryogen gas loss. The conical seat design allows exceptional flow, positive shut-off and less chance of debris accumulation in the flow path, all resulting in an overall longer service life. Maintenance on the packing and seat is quick and easy.

Reliable Performance in Extreme Cryogenic EnvironmentsWith a temperature range from -196C to +80C, the SKL Advantage Series Globe Valve features an extended bonnet for insulation against extreme cold. The valve's blowout proof stem and soft PTFE seat provide secure sealing, ensuring bubble-tight performance even under challenging cryogenic conditions. Its robust design and fire-safe structure guarantee dependable operation in storage, transport, and process systems for liquefied and gaseous industrial gases.
Comprehensive Standards Compliance and Safety FeaturesThis series is strictly engineered to meet BS 6364 and MSS SP-134 standards, with rigorous body and seat pressure testing rates to maintain safety and integrity. The valve incorporates anti-static devices and ergonomic, lockable handwheels to enhance user control. Markings for size, pressure, material, and flow direction ensure clear identification for operators in critical applications.
FAQ's of REGO Stainless Steel Globe Valves for Cryogenic Service SKL Advantage Series Long Stem:
Q: How does the long stem (extended bonnet) on the SKL Advantage Series Globe Valve improve cryogenic operation?
A: The extended bonnet (long stem) design insulates the stem from frigid media, reducing heat transfer and preventing freezing or condensation near operational surfaces. This allows for safe manual handling when used in cryogenic environments like LNG, LOX, LIN, and LAR.
Q: What types of connection options are available for installing these cryogenic globe valves?
A: The SKL Advantage Series provides ANSI/ASME B16.5 flange, ASME B16.11 socket weld, NPT threaded, butt weld, and socket weld ends to ensure compatibility with various piping systems commonly used in industrial gas processes.
Q: When is it necessary to use a Class VI (bubble-tight) leakage globe valve?
A: Class VI leakage (bubble tight) soft seat valves are essential in cryogenic applications where strict containment of gases is required, such as in storage, transport, or process systems handling liquefied or high-value gases to minimize losses and maintain safety.
Q: Where can the REGO cryogenic long stem globe valves be used safely?
A: These valves are suitable for use in cryogenic storage facilities, transport systems, and processing plants handling LNG, LOX, LIN, LAR, CO2, CH4, or N2O. Their marking and pressure ratings help operators identify appropriate usage in specific service conditions.
Q: What is the benefit of the ergonomic, lockable handwheel on these globe valves?
A: The ergonomic handwheel design enables low-torque manual operation for precise flow control, while the lockable option offers enhanced safety, preventing unauthorized or unintended valve adjustment in critical operations.
Q: How are body and seat pressures tested for these cryogenic globe valves?
A: Each valve undergoes body test pressure at 1.5 times the working pressure and seat test pressure at 1.1 times the working pressure, ensuring reliability, safety, and compliance with international standards before delivery.
