Don't buy another expensive timer or build a complex manifold! Simply attach our hose threaded Galcon Alternator Valve to your spigot or timer to instantly double coverage of your drip irrigation system.
- Outlet switches with each timer cycle
- Rugged, impact-resistant construction
- Ideal for remote applications
- Female hose thread inlet and male hose threat outlets
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.
- Allows flows up to 6 gallons per minute per outlet
- Operates in a pressure range from 14 to 140 PSI
- Low friction polymer construction
- Flow switches from outlet 1 to outlet 2 with each timer cycle
- Allow one minute of "recovery" time between timer cycles

- I love the function of this alternator valve -- it allows a single outlet timer to alternate sending water to one system on one cycle and another system on the next cycle. You can also manually switch it if you just want to test it. I had a little trouble when one blew apart, but Dripworks replaced it right away. It may have been cracked in assembly, but the others I have continue working just fine. The literature says it can handle up to 120 psi, but a pressure regulator may be a good idea. I love that it's simple, operates on water flow alone, and effectively turns a single outlet timer into a dual outlet timer. I have the timers set to water one system one day and another the next, but you could program your timer to water both systems in the same day just by having it operate twice a day.

- It works great and best part is that it runs on water pressure and does not reduce pressure much at all. Downside is overtime it starts to leak and I am not sure if the valve closes completely as I am now getting constant leaking from it down the line. So I had to get a replacement valve after about 2 yrs

- Most game changing item in my garden. Works every time. Gives me ultimate flexibility to run water under pressure further. Saves water under California drought conditions.

- Lasted less than 2 weeks here on the farm. Began sporadically not switching over, then after another week quit working altogether.
