Cryogenic Liquid Hydrogen Control Valve

Product Overview

The Cryogenic Liquid Hydrogen Control Valve is a high-reliability valve specifically designed for ultra-low temperature applications, enabling flow control and safety shut-off for liquid hydrogen, liquid helium, and other cryogenic media.

Constructed from extreme low-temperature resistant metals, the valve maintains stable mechanical performance and excellent sealing under temperatures ranging from −269 °C to 80 °C. It is suitable for DN10 to DN50 nominal diameters and Class 150 and Class 300 pressure ratings, meeting the demanding requirements of cryogenic research installations, hydrogen energy engineering, and deep cryogenic fluid systems.

Working Principle

The valve achieves flow control via precise fitting between the valve core (plug) and seat. When actuated, the driving mechanism moves the valve core, adjusting the flow path and controlling the on/off status of the cryogenic medium.

Both the valve body and internal components are made of 316L stainless steel, providing excellent low-temperature toughness and dimensional stability. The valve’s welded connection structure minimizes potential leak points and ensures system-wide sealing integrity.

The valve operates as an on/off type, with a leakage rating of Class VI, suitable for high-sealing requirements in extreme cryogenic applications.
