Material Compatibility:

Cast iron is a common material choice for marine check valves due to its strength and corrosion resistance. Ensure that the cast iron material is compatible with the fluid and environmental conditions of your marine application.

Size and Pressure Rating:

Determine the appropriate size and pressure rating of the check valve based on your system requirements. Ensure that the valve can handle the maximum flow rate and pressure expected in your marine system without causing excessive pressure drop or compromising safety.

End Connections:

Check valves come with different end connection options, such as threaded, flanged, or grooved ends. Choose the end connections that are compatible with your piping system and provide a secure and leak-proof connection.

Maintenance and Serviceability:

Consider the ease of maintenance and serviceability of the check valve. Opt for valves with accessible internals and simple maintenance procedures to minimize downtime and operational costs.
