About Valve Presettings

Explains the concept of valves in pipe network calculation for heating and potable water.

In the Valves dialog, select the valves to be used in the pipe network calculation. Data from different manufacturers are available for this purpose. Assignment of valve data is done automatically by preselection in the Valves dialog or by explicit local assignment at individual components. If multiple components have been added to the valve preselection for a valve type, the program calculates which component fits best and uses it automatically.

Valves added to the valve preselection (Valves dialog) are saved in the project including their technical data until they are removed from the preselection. Once a valve is removed from preselection it can no longer be used for calculation.

Install an appropriate data set to use the data from manufacturer systems. Manufacturer data sets can be downloaded via the LINEAR Installation Center.

Valves in the pipe network calculation of the scheme generator heating

Pipe network calculation entails the hydraulic balancing of the network. After dimensioning the pipes, valves are throttled to achieve identical pressure loss for all flow paths when viewed from the pump.

Valves in the pipe network calculation of the scheme generator potable water

Potable water- and circulating pipe systems require hydraulic and thermal balancing to ensure sufficient flow and necessary water temperatures in every pipe of all pipe runs. Regulating valves are used to that end.
