Rated 3.8 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by The ONLY valve to use!!!!! Have been replacing our old valves with these brass ones. THESE ARE THE BEST!!!! Long lasting (replaced in front yard a couple of yrs ago). A little more pricey - But WELL WORTH IT!!!!! July 12, 2016
Rated 2.0 out of 5.0 by Poor choice unless you fix the valve as described here Good brass body and valve parts. Bad design flaw causes valve to stop working after a year or so. It is not a bad coil. Once fixed as described here they are very reliable. The problem is that after a while, the rubber diaphragm blocks a small channel in the lower brass diaphragm chamber preventing the valve from actuating. To fix, cut a 1/4" x 3/4" piece from a 5mill brass shim stock, bend it about 3/16" from one end and slide it under the rubber diaphragm to cover the channel that is near the valve actuator after you remove the SS screws holding the diaphragm chamber together. Position the bend over the edge of the brass body so that it will be clamped against the diaphragm when you re-assemble the chamber. Bend the rest of the shim so that it follows the curve of the lower body. Careful to not block the small hole between the lower and upper diaphragm bodies. The shim covers the channel so that the rubber diaphragm will not block the control flow when the valve actuates. Works 100% of the time and makes the valve reliable. Just do it right away and save yourself problems later on. Once fixed, the valve is a good value compared to a Champion equivalent. Without the fix, forget it. August 17, 2014
Rated 4.0 out of 5.0 by Good Product - too bad they changed the shape so I had to add additional parts when replacing old an Orbit valve Like the brass however, it did not have the same dimensions as our previous valves. Both were 3/4 inch but the distance between the pipes was different and they ended at different heights. The old and the new were Orbit products...why not set a standard and stick to it? Very irritating. August 4, 2015
Rated 4.0 out of 5.0 by Material quality issue Thanks for the tip from "Engineer". I had a valve that wouldn't open unless I turned on the solenoid and opened it manually. Then it would stay on even when the manual pilot was closed. As can be seen in the photos submitted by "Engineer", this was caused by the rubber diaphragm swelling into the brass trough on the bottom of the valve and pinching off the pilot water flow. The brass shim cured this problem by lifting the swelled rubber out of the trough allowing the pilot flow from the solenoid valve to open the main valve. I went ahead and added a shim to my other 5 valves. Only one other valve had the swelled rubber that would have eventually pinched off the pilot flow, especially if the water pressure is high. The other 4 rubber diaphragms were fine and bridged across the top of the trough as intended. My opinion is that this wasn't necessarily a design flaw as much as a materials quality issue. When the valve was originally tested, the rubber didn't swell and this was not an issue. Orbit probably had a supplier material change and this new material exhibits the swelling behavior. My suggestion is that Orbit purge all defective rubber diaphragm parts from existing inventory and replace them with acceptable material. They should then replace any defective swelled parts for free from existing customers. This would insure their customers receive years of use from this high quality valve as they would expect. Also, the repair kit that has these large diaphragm parts is hard to find and ridiculously expensive, partly because it contains parts for both the 3/4" and 1" valves. May 3, 2015
Rated 4.0 out of 5.0 by Works great I installed 6 of these valves, and they worked great. I was concerned when I read the last reviewers comments, but I learned that the valves are not "leaking". The vavles are designed as a back flow preventer so that tainted water is not allowed to flow back into your clean water supply. When the sprinklers are turned off, any water left in the sprinkler lines that might flow back through the valve into the water supply is allowed to seep out onto the ground instead. This is the way the valves are supposed to work. If you don't want this water spillage, the valves should be installed on taller pipes so that the valve bodies are always a few inches higher than all of the sprinkler heads on its branch. I learned this in my plumbing class! September 6, 2013
Rated 5.0 out of 5.0 by Worth the cost I got tired of having the cheap plastic green actuators blow out and I should have followed my instincts and installed these made of brass to begin with. Once in, nothing to worry about. I only need the actuator but I buy the complete assembly for a few dollars more. I think just the actuator alone is too pricey. This is the third I bought, two more to go. August 5, 2014
Rated 5.0 out of 5.0 by Quality and Reliability I found these valves when I was replacing my old worn out ones. The previous valves were also Orbit, but they were the cheaper plastic ones. They had corroded and began to leak pretty bad. Being that my city had just raised water rates I wanted to be sure I wasn't being wasteful. These valves were the solution. They are very strong, cast brass. Installation was extremely simple, I unscrewed the old valves and screwed on the new ones (adding some PVC repair slides to make it easier). I turned the water back on and have not experienced any leaks. Wiring them up was simple as well. These valves are expensive, there is no doubt about it. The idea is that they will long outlast any plastic valve and the money you spend replacing those will eventually exceed this. It is a quality product. Knowing how valves work is necessary when installing and also when writing a review, previous reviews seemed to be a little misleading. May 4, 2014
Rated 1.0 out of 5.0 by 2 out of 3 Purchased Leak I purchased 3 of these valves for my front yard and had my Contractor install them. After install they seemed fine and leak/seep free. After 3 weeks; 2 of the 3 valves "Seep Water". Very disappointed that I have to buy new valves and pay my Contractor Again to re-install them; not to mention my Water Bills increased by over $100.00. If you buy these valves, you MUST check them every couple of days or you may be very surprised when your water bill comes! May 8, 2012
