I have a ball valve in a really tight spot that I would like to automate. I think I can get 30% more heat per burn cycle if I open this valve. Based on it's location, there is little chance of me taking it out and replacing it with a zone valve or Asco type valve. So, I'm looking for an electric actuator for a 1 inch brass ball valve. Preferably two wire control - power to open and remove power to close. But, I could rig up a relay to provide power for both directions. Cheap is good, too. Thanks for any advice.
