would this valve work

[StirCrazy]

1" AC Valve. Use with any of our AC controllers. Inlet and outlet are 1" Female Pipe Threads (FPT). Includes 24 VAC solenoid, manual on and off, manual bleed, and flow control. Operating pressure 10-150 psi and flow range from .2 to 35 gpm.

sorry forgot this part

well with a switching relay I was looking at you have 2 output sets. one energized and one off.. and it just switches them. so one would always be off while the other was on. and it says they are smooth opening so I am asuming that it takes a couple seconds to open and doesent slam. this I would have to confirm again.

what are you thinking of Darren? I was going to try that sinasoidal valve but I don't like a few things about it. and the delron would be as expensive as one of thease valves.
