The LNG Special Check Valve is designed to prevent reverse flow in pipelines handling liquefied natural gas (LNG) and liquid nitrogen (LN2). This valve, built from durable stainless steel and copper, ensures safe and reliable operation in ultra-low temperature environments, with a temperature range of -196°C to +85°C and a pressure rating of 4.0 MPa. It is ideal for LNG and LN2 systems, preventing unwanted backflow and ensuring the stability and safety of the pipeline.
With automatic operation, this check valve features flanged and threaded end connections, making it compatible with a wide range of systems. It adheres to international design and manufacturing standards, including API, ASME, ASTM, ANSI, BS, DIN, JIS, ISO, and GB, ensuring exceptional performance and reliability in cryogenic applications.
