accepts a 0-10vDC control signal
Had a bit more of a search using a variety of terms, unfortunately the search function doesn't like the term '0-10v'.Is this the kind of thing most people are using?http://ruggedcircuits.com/html/circuit__20.html
I think I may have left a vital piece of information out.The valve is 24vAC powered. The 0-10v is just a signal, I don't think the current draw is very high...The 0-10v input expects to see a DC input not a DC PWM. So I can't just give it a 0-10v PWM signal.
I found this circuit which is a 0-10v output. I'm pretty sure the triangle is an op-amp (LM358M) but what are the transistors doing?
One to buffer the output and another to limit its current.That circuit requires a 0-10v input.
