The solenoid that you show would work fine. It is "direct lift" rather than pilot-operated, so it will work with low pressure, and the plastic body shouldn't add anything undesirable to the water.
McMaster must have dropped the specific solenoid that I used, and now the link goes to their main page.
Rives:
that solenoid I am about to buy from amazon only have one way 1/4" female npt. Is that right?
I think yours is a two way, with two 1/4" female npt right?
