Product Description
| Model Name/Number | SKM Advantage Series |
| Brand | REGO |
| Body Material | Stainless Steel |
| Usage/Application | Cryogenic Liquids |
ApplicationThe 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 Oxide, Methane, Ethane, Ethylene, Argon and LNG . Our KoldSeal 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.

Precision Built for Cryogenic SafetyEngineered specifically for cryogenic service, the SKM Advantage Series globe valves accommodate temperatures as low as -196C, making them ideal for use with industrial gases, LNG, and liquid oxygen, nitrogen, or argon. The extended bonnet and anti-static features not only promote safe operation but also enhance insulation, reducing vapor loss and ice formation risks during low-temperature transfers.
Superior Sealing PerformanceWith a dual-sealing system using PTFE seats and a metal-to-metal backup, as well as Class VI (bubble tight) leakage specification, these globe valves prevent even microscopic fluid leaks. Their electropolished surfaces ensure no particulate contamination-critical for oxygen service-while meeting stringent cleanliness and low emission standards, ensuring operational safety and purity.
Comprehensive Compliance and User-Friendly DesignCertified in accordance with ISO 21011, EN 1626, PED 2014/68/EU, ASME B16.34, and BS6364, these valves deliver peace of mind regarding quality and safety. Features like reduced operating torque, blowout-proof stem, low-emission graphite/PTFE packings, and the option of manual handwheel operation ensure easy, dependable use in various process settings.
FAQ's of REGO Stainless Steel Globe Valves for Cryogenic Service SKM Advantage Series Medium Stem:
Q: How does the extended bonnet improve the valve's cryogenic performance?
A: The extended bonnet significantly enhances vapor insulation, reducing the risk of ice formation around the packing and handwheel. It keeps the stem seal area above the cold zone, ensuring smooth manual operation and minimizing the chance of leaks in cryogenic environments.
Q: What are the primary benefits of the Class VI (bubble tight) leakage rating?
A: A Class VI leakage rating ensures that the valve provides a total shut-off with virtually zero leakage, even with cryogenic media. This ensures safety, prevents product loss, and maintains process integrity-vital for handling industrial gases and liquefied gases like LNG or liquid nitrogen.
Q: When should a cryogenic globe valve with a metal-to-metal backup be selected?
A: Select a cryogenic globe valve with a metal-to-metal backup when additional sealing integrity and durability are required, especially during rapid temperature changes or in applications where PTFE seats might degrade over time. This backup system extends service life and guarantees reliable shut-off even if the primary seal is compromised.
Q: How does the valve's design facilitate maintenance and safety?
A: The rising stem design with an external thread keeps stem threads away from direct contact with media, minimizing wear and facilitating inspection. Features like the blowout-proof stem and anti-static construction further enhance operational safety and ease of routine maintenance.
Q: Where can these valves be installed, and what connection types are available?
A: These globe valves are suitable for installation in industrial gas pipelines, LNG facilities, and liquid oxygen/nitrogen/argon service lines. Connection options include socket weld, butt weld, threaded, or flanged ends, making them adaptable to a variety of piping systems and installation requirements.
Q: What compliance and design standards do these valves meet?
A: SKM Advantage Series valves meet international standards, including ISO 21011, EN 1626, PED 2014/68/EU, ASME B16.34, and BS6364. They are also certified to be fire safe, which underscores their suitability for critical and hazardous service conditions.
