Found some matches.
I first posted this elsewhere but thought some of you guys would appreciate it too.
I installed a needle valve, safety shutoff valve, and a solenoid valve with PID controller to maintain propane flow and smoker temperature to my masterbuilt 40 inch propane smoker.
I got the idea and inspiration for the safety shutoff and solenoid valve from glenwillits on this thread. So big thanks to glenwillits.
After initial install, I let it run to double check for leaks and to make sure the solenoid valve and PID were playing nice. It's been a couple weeks now and I did another test run today and my target temperature was 225. It was able to maintain +/-1 degree, 224-226F. I couldn't be happier with this setup. I can now truly set it and forget it, and if the burner flame happens to go out, the safety valve will prevent the smoker turning into a bomb.
Here are all the parts laid out before install. The Auber PID controller was the only thing i already had on hand.
The solenoid valve and needle valve assembled. The Auber has a built-in solid state relay, and it's 12v 1a output is able to control the solenoid valve directly. The needle valve portion controls the ”pilot light" aspect of the setup and is always on and dialed in to a lower temperature, eg 220F. The solenoid portion is normally closed, and the PID controller can open it for full propane flow in order to maintain the target temperature, eg 225F.
The smoker's burner assembly already had a hole that i used to mount the safety shutoff thermocouple.
Everything installed under the smoker.
Front view after installation. Safety shutoff is to the left of center, and to the right is the solenoid and needle valve.
