	Sprinkler valves are the most commonly used valve on pneumatic ~~launchers~~, and offer a number of desirable qualities. Because they are intended for use with home watering systems, sprinkler valves are readily available at nearly any location that sells PVC pipe and fittings. Sprinkler valves are intended for electronic actuation, however most are modified for pneumatic actuation, offering better performance in spudding applications.

	Unfortunately for spudders sprinkler valves are not designed to open quickly since the speed of the valve has little affect on their intended use in sprinkler systems. In addition the large number of internal turns decreases the flow by roughly 25% compared to a piston valve of the same seat diameter, though muzzle velocity only decreases by about 10%.

	A sprinkler valve can be actuated, or opened, in a number of ways. Though they are intended to be opened by the application of 24VAC to the solenoid, many opt for a modification allowing the [[pilot ~~volume~~]] to be vented through another valve. Typically a [[Blowgun]] is used, though ball ~~valves~~ and even other sprinkler valves can do the job.		A sprinkler valve can be actuated, or opened, in a number of ways.

	If your valve leaks air out the barrel there is a good chance that there is dirt, PVC shavings ''etc.'' in the valve preventing it from closing properly. An easy way to clean the valve it to just hook it up to a hose and flush water through it while cycling the valve a few times. If that doesn't fix the problem then you should disassemble the valve and clean the diaphragm and seat. Check for any plastic chips that may have entered the valve. Smear the diaphragm and seat with lithium grease to promote a seal.

	Although most sprinkler valves are intended to operate on 24VAC, they can be successfully opened with 9-27VDC, usually applied by one, two, or three 9v batteries. The power source is wired in series with the solenoid and a switch. The solenoid will retract and the valve will open when voltage is applied.
