I ended up getting the SMC VDW21-5G-2-01-L. The orifice size is 1.6, port size is 1/4. The only difference is this unit is designed for pure water and the amature assembly is corrosion resistant construction. I think it's safe for use with CO2?????
Alan, sorry didn't have time to check TPT,
it is 1/8 BST, not NPT
Please look into the detail on PDF.
What is everyones experience with the Fabco NV-55-18.
Ok,it is pretty convience because it is 1/8 npt ports ,but more others(better), you can get at lower price.

There are about three version of the SMC VDW solenoid PDF, the one Alan provide, I believe is the most detail and recent.
