How many sprinkler heads can this valve serve?

Asked by: angel
angel, that will depend on your water pressure, as well as the type of sprinkler heads you intend to install on the line. Please contact our Support team at 1-800-488-6156, and we'd be more than happy to help in any way we can. Thanks!

I have valve 57100 installed. can I still get the old styl 57100 valves?

I want to be able to replace parts without removing the valve.
Asked by: Mike
Mike, we sell our Diaphragm Repair Kit (#57045), which will work on 57100/57101 valves. That should give you the replacement parts you need. If not, please give our Support team a call at 1-800-488-6156, and we'd be happy to help. Thanks!

If I feed this with 1/2 inch will I cause significant lost in pressure to my impact sprinkler head. 1 head per valve.

Asked by: Tom
Tom, the recommended flow through a 1/2” PVC pipe is about 5-7 gallons per minute maximum, while the recommended flow through a 3/4” PVC pipe is about 8-11 gallons per minute maximum. Exceeding these recommended rates increases the friction losses in the pipe, so you will start to see different performance (meaning spray distance) between the first head to receive water and the last head on the line. Assuming that you only have one head on the line, though, you should be fine supplying our 3/4” valve with a 1/2” line as long as whatever sprinkler head you use does not flow more than about 7 gallons per minute.

What is the minimum amp of the 24vac transformer can be use.

Asked by: Tom
Tom, 24V AC solenoids (like the ones used on valves like this) require anywhere from 150-250mA to operate. Please feel free to contact our Support team at 1-800-488-6156 if you have any other questions at all. Thanks!

3/4 in. FPT Auto Inline NFC Valve is rated 3.9 out of 5 by 32.
Rated 5 out of 5 by from Quality Product I personally installed a 5 station in ground sprinkler system with four sprinkler heads per station using all Orbit components including 5 of these valves in 2010. There have been zero problems with these valves or any of the Orbit components. A little over a year past I added 2 more stations using Orbit components including these valves. I have had zero problems with my system. I am surprised at the negative reviews of this product. I am very mechanically inclined with a degree in Applied Science in Industrial Engineering and do a lot of Plumbing, Electrical and general construction projects. I have personally found that Orbit components, including these valves, are of good quality, long service and work as designed if properly installed and maintained. I highly recommend Orbit products as quality, cost effective and good value.

Rated 1 out of 5 by from Sprinkler valve I bought this valve to add to my existing manifold and after installation I turned the water on and the valve appeared to be open. I did my customary checks, is manual open: no, wires were not even connected at this point. I then took the top of the valve off looking for damage or debris in the diaphragm and going nothing. I tried the water and again it came out as if it was on. Yes, I did verify the directional arrows as well. After 3 attempts at taking it apart and checking with no results, I went to HD and bought another. I took the guts out and put them in the existing valve body and the problem went away. I have no idea exactly what the issue was but I did spend a whole day trying to find out. This was the first time I went with this brand. I usually use a commercial brand. I do hope it lasts because if the entire valve ever has to come out it is a lot of work.

Rated 5 out of 5 by from A sturdy, easy to install valve This is the first time I've used orbit products. I have often used similar products by competitors. From what I've experienced, this valve can stand up to and exceed quality and pricing. Definitely a winner.

Rated 5 out of 5 by from Water valve The valve worked great. Easy on installing. However this was the exact valve I took out so that made things easier.

Rated 1 out of 5 by from i bought 10...4 bad...dont buy I bought 10...4 leaked ...I followed instructions from the orbit video to clean and clear the valves but they still leak every other time they turn on...and...you cannot unscrew and screw in the bolts a lot...it's plastic...one even cracked at the seam after 1 hour of installation...my advice... look for a better unit...and...do not get a screw in type but a glue in type valve...you can't reuse the plastic threaded parts anyway if you have to take thinks apart ...I live in a place where I have to haul my own water and leaky valves cannot be tolerated...home depot did a great job on delivery...it's the orbit valves that are bad
