This refers to pneumatically modifying a sprinkler valve to actuate via a different pilot (is this the correct terminology?) - typicaly a blowgun, although larger valves (1.5-2" and up) require something with more flow to preform well. The larger vent decreases opening time, and does not require batteries like the stock solenoid.
Recent research by ssb73q of the SGTC indicates that using a small QEV as the pilot increases muzzle velocity and the consistency thereof. This is most likely because the time it takes to open is not variable, in contrast to a human opened blowgun.
