hey all,
I am trying to figure out what kind of circuit I need to control a proportional solenoid valve. here is a link to the valve in question....
Soolenoid Valve
I was thinking I could use somthing like this...
MOSFET
driven from a PIC18xxx PWM to drive the valve. I would need 0% duty cycle (0v) coming from the PIC to equal 0v to the valve and 100% duty cycle (5v) coming from the PIC to equal 12v to the valve. basically, output would be proportional to duty cycle.
This will be used on a hydraulic pump trailer (to control flow) with a 12v system very similar to a car.
Any thoughts on design or help on choosing components in this situation would be much appreciated. I have never designed anything like this before.
Thanks.
