Orbit 57280 3/4" FPT L-Series Automatic Sprinkler Valve

Installed a month ago. No problems so far.

I used these valves with my otherwise Rainbird™️ system. They work great and are a good price. I used doubled pairs of cat5e cable as control wire to my contriller. My controller supply is 26.5VAC@650mA. I connected these to garden hose instead of PVC. It's important to note that these are threaded as female pipe thread, not female hose thread. I used an FPT > FHT on either end and a MHT > MHT union on the outlet end. If you can find an FPT > MHT adapter, you could do it with one less fitting than I used. I have a regulator upstream of these to keep it around 85psi at the spigot, but have tested briefly at 112psi(my house pressure is unreasonably high because of the sediment level in our water) with no leaks.

We live in the "high desert" of CA, annual rainfall is about 10", and that is mostly in the winter. I put together a 6 manifold system. The controller has a glitch, it won't let you program #5 and #6 unless you start with #1 and reset (or maintain) the settings and just go in order. I have them in a little shelter so they do not get any sun and are at an easy hight to work with. They all worked for the first six month growing season. Two did not survive the winter, although I thought I had drained all of system. I replaced them. NONE of them survived the second winter although after I turned the water supply off, I left the system on for a day to be sure it drained the valves. Two will not turn off, 4 will not turn on. I did all the things the on-line fixers recommended, even buying 2 new solinoids, which did not solve the problem. So, I am buying new ones, same model, since they will be easy to plumb in, I think this winter I will take them out of the system and put them where freezing is not an issue, and put a drop of oil on the solinoid. The cost is small compared to the value of vegetables we grow, let alone the flowers and shrubs. My experience with Chinese products is that quality control is missing, so sometimes you get a good one, sometimes you do not - 10 electronic things failed in my new Audi - all made in China - in the first 50,000 miles, none of the replacements have failed in the second 50,000 miles. 3 of the 6 have failed, and, and 3 are going into their next season. Well drained when turned off, no water in lines in or out.

Good...

Replaced damaged valve with exact valve needed. All zones work now as a result!

This is a great valve. Easy to install, easy to adjust. However, it has a design issue that could be a problem for you. The valve needs to see a differential pressure between the supply side and the output side for the solenoid to function properly. If the irrigation line has very little flow, like, just a few drippers, the valve may not turn off. With larger flow rates, the valve operates perfectly. If your water supply is dirty or sandy, you may need to put a pre-filter in front of the valve, because it won’t tolerate much debris in the valve feed chamber before it fails to operate and requires cleaning.

I had a pretty bad leak on one of my valves due to a damaged diaphragm. I used this to replace the entire valve on the bad valve on my Orbit 57253 3 valve system. This was a very easy fix thanks to the easy detachable parts and I no longer have leaking sprinkler heads. My only complaint, not really related to this product is, a replacement diaphragm is 50-60% the cost of an entirely new valve.

Work way better than the older designs, they always seep and I replace with these. Do yourself a favor and install the manifold with unions and replaceable orings

Was a perfect fit Exactly as described Now my sprinkler system works flawlessly

Me gustó el precio y funcionalidad, pero solo han durado 2 años ahora se mantienen las válvulas abiertas y no cumplen con su función, en comparación con la competencia duraron poco

buen producto

Does what it should and no complaints.

Cost is high
