Cryogenic Insulated Check Valve
Superior Insulation: Our Cryogenic Insulated Check Valve is meticulously designed with advanced insulation materials that provide exceptional thermal resistance. This insulation effectively minimizes heat transfer, ensuring the proper preservation and integrity of cryogenic fluids.
Enhanced Reliability: Featuring a robust construction and precise engineering, our valve offers reliable and consistent performance, allowing for precise flow control and preventing any undesirable backflow of cryogenic fluids. With its high-quality build, our Cryogenic Insulated Check Valve provides optimal reliability even in the most extreme low-temperature conditions.
Optimal Safety: Ensuring the safety of operators and the environment is a key priority in cryogenic operations. The Cryogenic Insulated Check Valve incorporates safety features such as pressure relief valves and leakage monitoring systems. These critical safety features prevent overpressure situations, mitigate the risk of leaks, and maintain a safe working environment.
Customizability: We recognize the diverse needs of our customers across industries. Hence, our Cryogenic Insulated Check Valve offers customizable options to meet specific requirements. Our skilled engineering team works closely with clients to develop tailored solutions that align with their unique needs and applications.
Product Application
The product series of Vacuum Valve, Vacuum Pipe, Vacuum Hose and Phase Separator in HL Cryogenic Equipment Company, which passed through a series of extremely strict technical treatments, are used for transferring of liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, LEG and LNG, and these products are serviced for cryogenic equipment (e.g. cryogenic storage tank, dewar and coldbox etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, pharmacy, biobank, food & beverage, automation assembly, chemical engineering, iron & steel, and scientific research etc.
Vacuum Insulated Shut-off Valve
The Vacuum Insulated Check Valve, namely Vacuum Jacketed Check Valve, is used when liquid medium is not allowed to flow back.
Cryogenic liquids and gases in the VJ pipeline are not allowed to flow back when cryogenic storage tanks or equipment under safety requirements. The backflow of cryogenic gas and liquid may cause excessive pressure and damage to equipment. At this time, it is necessary to equip the Vacuum Insulated Check Valve at the appropriate position in the vacuum insulated pipeline to ensure that the cryogenic liquid and gas will not flow back beyond this point.
In the manufacturing plant, Vacuum Insulated Check Valve and the VI pipe or hose prefabricated into a pipeline, without on-site pipe installation and insulation treatment.
