I am looking for a couple of 12VDC 3-way stainless universal solenoid valves for water use with little success.  They need to operate in the 20-30 psi range but have a proof pressure above 1,000 PSI.  (The HP pump will be locked out and system pressure reduced before the valve operates.)

Other requirements are:
3/8" NPT fittings preferred on one and 3/4" on the other.
CV > .7

I found a Red Hat that would work but can't find anything about the maximum pressure it can take.
Any suggestions on where to look would be greatly appreciated.
