When choosing a check valve, the following factors need to be considered:
Medium characteristics:
Factors such as temperature, pressure, and corrosiveness can affect the material and structural selection of check valves.
For example, for corrosive media, check valves made of corrosion-resistant materials such as stainless steel and alloy steel should be selected.
Pipeline parameters:
The parameters such as nominal diameter, working pressure, and connection method need to be matched with the pipeline system.
Ensure that the diameter of the check valve is consistent with the diameter of the pipeline, and that the working pressure meets the requirements of the pipeline system.
Installation location:
Check valves should be installed on pipelines that require prevention of medium backflow.
The valve disc should be installed in the direction of the medium flow to ensure that the check valve can work properly.
Maintenance convenience:
Choose check valves that are easy to maintain and repair to reduce maintenance costs in the later stages.
Considering the structural complexity and maintenance difficulty of check valves, choose the type suitable for on-site maintenance.
