Thanks for the reply. I am looking for something more substantial. I am working with coils in the 10 to 25 ton range and I am looking for valve sizes of 1 1/2" on up.

OK, understood, I'll see what we can find.

Honeywell V5011 series valves with a ML7421 series actuator will give you 0-10 VDC, 2-10 VDC or 4-20 ma control. A simple, yet highly accurate controller would be a Honeywell T775 controller.
