Depending on who you ask, they're all usable.

A search will show recent forum activity on types and ratings, and the subsequent ignoring of mfr's recommendations by some.

This is the their whole list.

There are small brochures on each family of 4 digit numbers in pdf. form also.

NOTE: There is a difference in 'Solenoid Valves' and 'Fuel, Gas and Oil Products', in the blue menu on left of main page.

When I called I was advised to use the 8214 family. Specifically 8214G020 in 1/2"NPT. List =$130.
It's just not cheap and common on Ebay...

Others will say that the ones for inert gas, water and light oils are suitable.
