The proportional valve V106 (1) is a directly actuated 2/2-way valve for flow control
of fluids. It can be used as a adjustable remote element in open- or closed-loops.
The valve pistons lifted of its seat as a function of the solenoid coil current and
releases the flow through the valve.

Controlling element proportional valve V106
The control electronic of the proportional valve is activated with a binary output
(O4 at XMA1). A analog signal from channel 1 (UA2 at X2) is driving the signal input
of the proportional valve with a standard analog signal from 0 to 10 V.
The standard analog signal is transformed into a pulse-width modulation (PWM) and
the opening of the valve is infinitely adjustable. The frequence of the PWM can be
adapted for different valve types.
