Valve Types
In this dialog valve types can be defined, which are available for the entire network calculation and simplify the production of a network substantially.
Hydraulics Tab
- Kind of characteristic – In this selection box the kind of characteristic of the type of valve can be specified. The following entries are available:
- Kind of characteristic – Comment
- Percentage equal – Input of the KVS value required.
- Linear – Input of KVS value and KVS/KV0 required.
- Freely defined – Input of up to 10 bases of the valve characteristic. The input fields KVS and KVS/KV0 are ignored.
- Check valve – No input of parameters possible. The effect of the parameters on the network calculation is described under Valves.
- Price categories – Assigns costs for the possible price categories to the valve types. The categories 1 to 6 are available across the application and can be filled according to your own needs.
- Valve position and coefficient – If the type of characteristic "freely defined" was selected, then up to ten bases can be entered in this field.
- KVS – Flow with standard conditions (20 °C, 1 bar pressure loss).
✍ The input field is to be filled out for the types of characteristic "linear" and "equal percentage".
- KVS/KVO – Theoretical positioning requirement. The input field is only to be filled out for the type of characteristic "linear".
- Characteristic – As soon as the type of characteristic "freely defined" is selected, the valve type receives its hydraulic characteristic with value pairs of position and valve coefficients. At least 2 and a maximum of 10 value pairs are to be entered into the list. Intermediate values are interpolated linearly by the program. The values can be entered unsorted, but must result in a strictly monotonous rising characteristic.
