Default Re: FAV valve specs

I have a better explanation:

Proportional valve is similar to a tap.
Flow is controlled by restricting the flow path. Pressure will vary with flow.

PWM valve is similar to a on/off button.
Flow is controlled by the ratio of the press/un-press duration. Peak pressure remains the same.

Since peak pressure is maintained for best atomisation, PWM valve is preferred.
