Full Port vs Reduced Port Sizing Considerations
When discussing standard sizes, it’s important to understand the distinction between full port (full bore) and reduced port (reduced bore) configurations, as this affects flow characteristics and the effective size of the valve. Carilo Valve stocks both configurations across their standard size range, allowing clients to select the appropriate valve type based on their specific flow requirements and pressure drop tolerances.
Full port valves feature an internal bore diameter equal to the pipe size, allowing unrestricted flow and minimizing pressure loss. Reduced port valves have a smaller internal bore, typically one size down from the pipe connection, which reduces manufacturing costs but creates some flow restriction. The choice between these configurations depends entirely on the application’s flow requirements, with full port being preferred for applications where flow velocity and minimal pressure drop are critical.
Material-Specific Size Availability
The standard sizes available can also vary based on the valve body material, as different alloys and metals require different manufacturing approaches. Carilo Valve’s inventory includes:
