Applications requiring prevention of backflow in pipelines.
High-temperature, high-pressure media: e.g., high-pressure steam, high-temperature/high-pressure oils.
Cryogenic (deep-cold) media: e.g., liquid nitrogen, liquid ammonia.
Low-pressure large-diameter applications: e.g., water supply systems, sewage treatment projects. For low-pressure, highly corrosive media, fully lined check valves may be selected. Valves with different material combinations can be chosen based on specific pressure, temperature, medium, and operating conditions.
Installation Position: Swing check valves are suitable for horizontal pipelines; if installed vertically, the flow direction must be upward. Lift check valves are only suitable for horizontal pipelines. Vertical check valves are only suitable for vertical pipelines where the medium must flow upward.
