China VJ Check Valve
Reliable Backflow Prevention: The China VJ Check Valve is engineered to offer reliable backflow prevention, ensuring a unidirectional flow of fluids. Its advanced mechanism allows fluids to flow in one direction, preventing any unintended reversal that could lead to operational disruptions or potential damages.
Durable Construction: Designed for longevity, the China VJ Check Valve is built using high-quality materials, making it resistant to corrosion, wear, and extreme temperatures. Its robust construction guarantees trouble-free performance over extensive usage, reducing maintenance costs and downtime.
Easy Installation: We understand the importance of quick and efficient installation processes. The China VJ Check Valve features a user-friendly design, facilitating easy installation and saving valuable time during initial setup and subsequent maintenance tasks.
Low Pressure Drop: Our check valve incorporates an optimized design that minimizes pressure drop, allowing for efficient fluid flow. By reducing the energy consumption required to maintain pressure, it promotes cost savings and maximizes overall system efficiency.
Versatility: The China VJ Check Valve is highly versatile, capable of accommodating various fluid types, temperatures, and pressures. This adaptability makes it suitable for a wide range of industrial applications, providing reliable backflow prevention under diverse operational conditions.
Exceptional Customer Support: We value our customers and strive to provide unrivaled technical support. Our dedicated team of experts is readily available to address any inquiries, provide guidance during installation, offer troubleshooting assistance, and ensure ongoing maintenance support throughout the product's lifespan.
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.
