If it works then we would be looking at about 800-1000 units a year. We are going to automate the valve with a fast acting solenoid (110V push/pull & spring) so we can close and open the valve in 0.5 seconds. If there is a threaded adapter needed for the stem I would also need 2 of those. I can sen a picture but I need and email.
