General

The control valve defines pressure P1 in front of the component according to the following rules:

P1 = P2                     for  P2 >= P1MIN

P1 = P1MIN              for  P2 <  P1MIN

Along with these rules, the following relations are also applicable for the pressure calculation:

H1 = H2    and    M1 = M2

As these components can also be used as a valve, the design of these components can be toggled between flap and valve.

Component 68  (valve):

This component functions like component 59 with the difference that the holding pressure P1MIN can be changed by means of a control connection.
