Dear All,
This is my first post here. I am looking to make a proportional valve controller for regulating the flow in 2 separate channels.
The channels are supplied by the same pump and I just want to place 2 valves on each channel to proportionally control the flow.
Since I am new to microcontrollers, I came here looking for some help on getting started with this project.
The valves I am looking to use are from Clippard (http://www.clippard.com/products/electronic-valve-proportional).
My specifications are selected from this page (http://www.clippard.com/cms/wiki/evp-selection-tips).
0-20 V, 218 Ohm coil, max. 0.093 A for the valve which has max. flow rate of 22 l/min and max. pressure handling of 100 psig.
1800 mbar pressure from the pump with free flow rate 13 l/min.
It says on the valve page that I can use proportional as well as PWM control. Which microcontroller board would be best for such an application (for both proportional and PWM)?
Any help with the circuit will be greatly appreciated.
Thank you so much for your time.
