The unique Alternator Valve can be used in conjunction with automatic tap timers that have multiple automatic starts or as a stand alone unit.

This Alternator Valve is not a timer, and does not require batteries or a power source. It is simply powered by the water moving through it. Place the Alternator Valve downstream of a timer or valve and it will alternate the water flow from one outlet to the next with each timer cycle. It is a simple, inexpensive solution to double the coverage of your drip irrigation system.
