nice but early versions may leak in time
I bought several of these as water control valves for a water source heat pump. They worked fine for a year or so. They then began to leak to the outside. It was evident that the diaphragms were not being clamped by the housing well, probably due to the rubber material shrinking. I contacted Orbit and they were great. They sent me a pair of replacement diaphragms. The new ones are a little thicker* at the sealing perimeter (looks like the ridges on the perimeter are now designed to bottom out in the seal groves) and are of transparent silicone, as opposed to milky silicone of the original. I noted that the new diaphragms are part number 57473-04 "S/A, diaphragm, jar top". What I see on-line as replacements are milky white and the same number without the "-04". (I think this needs to be cleared up that replacement diaphragms are of the improved design) With the new diaphragms all is well again but I'll know better in a couple of years :-) My guess is they will do fine...

Working great so far!
I ordered these valves for a purpose different than intended. I use them for air control for air cannons in a haunted house. They have worked great so far and I will buy more as I need them. The delivery was quick with no problems.
Do not be fooled by a lower price
I was warned about these valves. The operation is so simple that I could not fathom why they would fail. My initial 8 zone system took 11 valves to cobble 8 valves that would not leak. Three weeks into use, and i decide to check my valve boxes, I am glad I did 2 valves leaking. I have now replaced all 8 valves with Toro and could not be more pleased. Buy good valves, you won't be sorry. The time, and money I have wasted on crappy Orbit valves is time and money I will never get back.
