3 Way Valve Selection Question

[Equiplace]

I'm hoping someone could suggest where to look for a small, lightweight butterfly style 3 way water valve that could be actuated by a dashpot.

I am trying to divert a 6gpm, very low pressure @ 1/2"npt from one direction to the other (45 to 150 deg f). I prefer it to be acuated by 15psi air but the pneumatic vavles I see require at least 30psi.

I did find a 12v solenoid style that I could adapt but it is a litle heavy and large due to it's high pressure capability. It also acts instantly without smooth or adjustable transition.

Thanks in advance

Equiplace,
I'm afraid I didn't get the meaning of your question... Are you looking for butterfly valves having diameter 1/2"? Any way, 3-way butterfly valves?
I hope you can give more explanation.
Thank you, 'NGL

For a diverting set-up you can use two butterfly valves on a tee with one actuator and linkages. This has worked for me in the past. However it is very hard to find a butterfly under 2". How about a 3-way ball valve??
