How can I use PWM to control a Solenoid Valve through a PLC?

    I am looking at controlling the flow-rate of one liquid through a Solenoid Valve in a closed loop system, which takes input from another stream of liquid.

    Objective is to mix the two liquids at the right concentration downstream.

    I was able to source a PWM enabled valve, but how do I send the PWM signals to the valve? I have read about Controllers and Drivers, but don't understand too much as I am not from an Electronics background.

    Any guidance would be appreciated. Thanks :)

    You might want to mention and link to the specific parts. Odds are that the valve has a suggested PWM driver for it and a datasheet for that with instructions to aid in implementation.
