Is this a control valve or just a discrete on/off valve?

I am going to be using a Honeywell safety valve to control the burner.

I don't believe these are modulating valves so you really cannot control gas flow. What you really need is a Modulating gas valve.

A PID loop controller will not do that. What you need is a 24v power source that you can turn on and off by opening/closing a contact of some sorts.

yes a pid will do that. you will need the honeywell 24vac converter. I think others have recommended the auber 2352, im still researching which pid i want, i will be building the same setup as you. you will just run the pid in on/off mode.

So what are you guys doing then? Just using the loop controller to monitor temperature?

Nevermind. I now realized what you are doing. Sorry. I was thinking you were wanting to modulate gas flow using a control valve.

So really any pid will work even the SSR units if you add a relay to the control output? I would just need to set it to on/off control? What about if I just wanted to monitor the temp? I can't find a 1/16 din unit that will do that with out control.
