Cryogenic Gate Valve

Name: Cryogenic Gate Valve
Brand: SAVVY IMPORT AND EXPORT CO., LTD.

Cryogenic Gate Valve is engineered for reliable shut-off service in ultra-low temperature applications involving LNG, LPG, liquid oxygen, liquid nitrogen, liquid hydrogen, and other cryogenic media. Designed with an extended bonnet to protect stem sealing from extreme cold, it ensures long-term sealing integrity, low operating torque, and dependable performance. It is widely used in LNG terminals, air separation plants, petrochemical facilities, and industrial gas processing systems where safety, durability, and leak-tight performance are essential.

Extended Bonnet Design for Cryogenic Service

Features an extended bonnet that thermally isolates the stem packing from cryogenic temperatures, preventing seal freezing and ensuring reliable packing performance.

Designed for Ultra-Low Temperature Applications

Engineered to operate safely in temperatures down to -196°C (-320°F), making it ideal for LNG, liquid nitrogen, liquid oxygen, liquid hydrogen, and other cryogenic media.

Self-Draining Bonnet Cavity

Bonnet geometry is designed to prevent cryogenic liquid accumulation, reducing the risk of pressure build-up and freeze-related damage.

Cryogenic-Compatible Packing System

Special low-temperature packing materials minimize leakage while maintaining sealing integrity through repeated thermal cycling.

Low-Temperature Toughness Materials

Manufactured from austenitic stainless steel or other cryogenic-rated alloys that retain excellent impact strength and ductility at extremely low temperatures.

Reduced Thermal Stress During Temperature Cycling

Optimized body, bonnet, and wedge design accommodates rapid cooling and warming cycles, minimizing deformation and extending valve service life.

Suitable for High-Purity Cryogenic Media

Internal surfaces can be cleaned and prepared for oxygen or high-purity gas service, helping prevent contamination in critical applications.

Ideal for LNG Storage and Transportation Systems

Specifically developed for cryogenic process lines, LNG terminals, air separation units (ASU), bulk storage tanks, and industrial gas distribution networks.
