Stainless Steel High-Pressure Cryogenic LNG LOX Petrochemical Application Globe Valve

I. Product Overview

NEWWAY stainless steel cryogenic globe valve is a high-performance industrial valve designed for harsh operating environments, particularly suited for handling low-temperature, ultra-low-temperature, and high-pressure media. Engineered with precision, this valve integrates advanced materials, robust structural design, and versatile operation modes to meet the stringent requirements of industries such as oil and gas, LNG terminals, petrochemical plants, and general industrial applications. Its core design focuses on reliable flow control, excellent sealing performance, and long-term durability, making it a critical component in systems where media stability and operational safety are paramount.

II. Key Attributes and Specification Parameters

1. Basic Attributes

Material: The valve body, bonnet, and other pressure-bearing components are constructed from high-quality stainless steel, with 300 series austenitic stainless steel used for ultra-low-temperature applications (-101℃ to -196℃) due to its moderate strength, excellent toughness, and superior processability. For low-temperature grades (-46℃), low-temperature carbon steel is employed, ensuring optimal performance under specific temperature conditions.

Pressure Rating: Available in multiple pressure classes to accommodate diverse industrial needs, including 150lb, 300lb, 600lb, 900lb, and up to 1500lb, enabling safe operation in high-pressure systems such as LNG terminals and petrochemical pipelines.

Port Size: Covers a wide range of nominal diameters (DN) from DN20 to DN150, with extended options up to DN500 to meet various pipeline size requirements.

Temperature Range: Designed to handle media temperatures across low, medium, and normal ranges, with ultra-low-temperature capability down to -196℃, suitable for cryogenic media like liquid nitrogen, LNG (liquefied natural gas), and LOX (liquid oxygen).

Media Compatibility: Versatile for use with multiple media types, including oil, water, steam, gas, and acid, ensuring adaptability across different industrial processes.

Operation Modes: Supports multiple power sources for flexible operation, including electric, manual, hydraulic, and pneumatic, allowing users to select the most appropriate mode based on system design and operational needs.

Connection Type: Available with flanged or welded connections, ensuring secure and leak-free integration into pipeline systems. Flange drilling conforms to PN10/16 standards for compatibility with industry-wide pipeline specifications.

Structure: Features a through-way design, optimizing flow dynamics and minimizing pressure drop during operation.

Warranty: Backed by a 2-year warranty, guaranteeing reliable performance and providing peace of mind for long-term industrial use.
