The next step up from a ball valve, this is essentially a commercially produced diaphragm valve. However, they are unfortunately designed to open relatively slowly to prevent "water hammer". The performance can be improved by replacing the stock solenoid-valve vent with a pilot valve with more flow. Most often this is a blow gun, although for larger valves a ball valve or even a smaller sprinkler valve can be used. This operation is often called modding the valve.
Troubleshooting
If you are having problems with your sprinkler valve, these are some things to try
Valve "Honks"
You need a larger pilot valve. For more information, see honking.
Valve won't seal
If your valve leaks air out the barrel, you should disassemble it and clean the diaphram and seat. Check for any plastic chips that may have entered the valve. Lube the diaphram and seat with lithium grease to promote a seal.
