Diaphragm solenoids are good for high-flow. The orifice is usually as large as the plumbing.
Pilot-actuated solenoids are what you'll usually see for high pressure applications.
Direct acting are for low-flow, low-pressure. The orifice is usually much smaller than the plumbing, and the maximum operating pressure with the largest orifice might only be 50 PSI.
FWIW, I use the GC high-pressure 3/8 solenoids for spot-free, 450 PSI to the bays, 3/8" Dema diaphragm for city-pressure rinse to the pumps, and 1/4" Kip for soap/wax to the pumps and the low-pressure for the bays. I have almost no problems with any of those valves.
