Well, as some of you know I had to send my brand spakin' new Buna-N sealed Burkert solenoid back to the Burkert engineers in Charlotte, NC because, after installing it on my new VTS253A-1993 regulator, the gas flow would not shut off (the valve would not close).
I'd power the solenoid on and gas would flow normally.
I'd disconnect the power cable and the gas would still flow at 4+bps (The solenoid is suppose to close when the power is off and the gas flow is suppose to stop).
The leak was so bad, I could hear a hiss comming through teh solenoid when it was suppose to be shut!
It turns out, and some of you may know this (but I didn't), that despite the solenoid being called a "2-way" solenoid, it is only designed to have gas flow pass one way.
The problem according to the Burkert engineers was that I plugged my solenoid in backwards!
SO to avoid this same problem, I have decided to do another DIY to show you how to switch the solenoid around into the right position--where the gas flow is going in the right direction.
Here is what Dan sent when I asked him about the solenoid being "2-way.":
And no, the P = pressure port, the valves ore not identical on each side, the pressure side is ported to the spring on seat.
