It is a standard unit used to define the size of a pipe or fitting in a metric system.
- DN in millimeters (mm) indicates the approximate internal diameter of a pipe.
- For example, DN50 corresponds to a pipe with a nominal diameter of approximately 50 millimeters.
Inch pipe diameter refers to the size of a pipe, typically described using the Nominal Pipe Size (NPS) system in the imperial (inch-based) measurement system.
The seat bore combination of a valve refers to the internal diameter of the opening through the valve seat, which allows the flow of fluid when the valve is open. It is a critical dimension that influences the flow capacity. Based on your application data the right SB is advised.
The Kvs of a valve is a key performance parameter that defines the valve’s flow capacity. It indicates the volume of water (in cubic meters per hour) that can flow through the valve at a temperature of 5–30°C with a pressure drop of 1 bar across the valve in the fully open position. Based on your process data the best Kvs value is advised.
This is the percentage of valve opening under the given process conditions, based on the Seat Bore/Kvs and diameter. A percentage of 50% indicates that the valve will operate at 50% opening under these conditions.
The score indicates the best option for the specified process conditions, ranked from 0 to 100%. If you would like to learn more about the best score or option for your needs, please press the ‘Send Inquiry’ button to get in touch with us!
