Check Valve Or Non Return Valve


Check valves play a crucial role in ensuring the desired flow direction in pipelines by preventing undesired return flows. In the cryogenic field, specialized check valves are necessary to meet the requirements of extremely low temperatures. These cryogenic check valves are designed to maintain efficient operation even in sub-zero conditions.

At our company, we offer cryogenic check valves that provide reliable and secure flow control in cryogenic systems. These valves are specifically designed to withstand temperatures well below the freezing point, ensuring optimal performance in cryogenic applications.

Our cryogenic check valves are available in sizes ranging from DN10 to DN200, accommodating various pipeline requirements. They are designed to handle pressures of up to 50 bar, making them suitable for high-pressure cryogenic environments. Operating temperatures for our cryogenic check valves range from -196°C to +120°C, ensuring reliable performance in extreme cold conditions.

By incorporating our cryogenic check valves into your pipelines, you can effectively prevent backflow and ensure the desired flow direction of gases and liquids. Our valves are engineered to meet the stringent demands of cryogenic applications, providing efficient and reliable flow control in freezing temperatures.

Choose our cryogenic check valves for their quality construction, durability, and ability to maintain optimal flow control in cryogenic systems. We prioritize the performance and safety of our valves to meet the specific requirements of cryogenic applications.
