Default Re: FAV valve specs

Proportional valve are also known as v"ariable lift" valve, the position of the valve is suspended between to two poles, the position of the valve is carefully controlled by a electronic servo-feedback loop driver running at a several hundred Hz. The valve design requires a very narrow hysteresis megnetic circuit.

A variable lift valve is very similar to a pump speed system, low speed=low pressure=low flow=low atomisation.

The aquamist FAV is a (fixed lift) valve responding relatively linearly between 25-50HZ PWM drive signal.

Aquamist PWM FAV (fixed lift, constant line pressure):
Full pressure (good atomistion) at wide range PWM%. It requires a relatively simple control driver. All fuel injectors use this type of valve.
