| Thanks for the detailed pics. What I'm dealing with is a PWM valve that controls the hydraulic flow to the product pump. It still responds to the flowmeter and speed as does the flow control valve that you have, but does so by altering the pump speed/pressure. My issue is that it will not respond when in operation. I can manually make it increase/decrease in test mode. It has worked for several years in the past. I guess it has retired now. I need to figure it out.
I choose PWM where yours says "Standard".
