Mixing valve Xp

The proportional band defines within which change of the control variable x (T of the

 

flow) the whole correcting span y (valve travel) is traversed.

 

The smaller the proportional band, the greater the change of the manipulated variable

 

y at a given change of the controlled variable x.

Mixing valve Tn

The integral action time is the period of time the controller’s I-part would require to

 

produce the same change of the manipulated variable as the P-part
