Liquid Helium Check Valve
Precise Flow Control: Our Liquid Helium Check Valve enables accurate control of liquid helium flow, ensuring optimal performance in cryogenic systems. With its efficient design and reliable functionality, it enables users to achieve precise and consistent flow rates for enhanced operational efficiency.
High-Quality Materials: Crafted with premium materials, our check valve is built to withstand extreme temperatures and demanding cryogenic conditions. This guarantees longevity and reliability, reducing the need for frequent replacements or repairs.
Excellent Sealing Performance: Our check valve is equipped with advanced sealing technology to ensure a tight and secure seal. This prevents any leakage and reduces helium loss, promoting efficient cryogenic operations and minimizing costly gas wastage.
Customizable Options: We understand that different applications require specific configurations. Therefore, we offer customizable options for valve sizes, pressure ratings, and materials. This allows customers to select the most suitable configuration that aligns with their unique requirements.
Rigorous Quality Assurance: At our manufacturing facility, we carry out rigorous testing and quality assurance processes to ensure that each Liquid Helium Check Valve meets and exceeds industry standards. This ensures that our customers receive a reliable and high-performing product that withstands the demands of cryogenic 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.
