In terms of structure, the dual-plate check valve features a compact design with two symmetrical valve discs. This structure reduces flow resistance and ensures quick closing responses. The lift check valve adopts a vertical disc movement structure, which provides tight sealing performance, especially in pipelines with strict leakage requirements.
When it comes to usage, check valves need to be installed in the correct flow direction as indicated by the arrow on the valve body. They should be placed at the outlet of pumps or the end of pipelines to prevent backflow effectively. Regular inspection of valve discs and springs is necessary to maintain their functional reliability.
Common material options include PVC, brass, and stainless steel. The material choice depends on the specific working conditions, such as pressure, temperature, and corrosion requirements.
Stainless steel check valves are highly recommended for high-temperature and high-pressure environments, such as chemical processing equipment.
