Hi, I have Orbit valve for a section of my yard. The pressure is really low when I turn it on with my remote. When I turn it on manually at the valve, the water pressure is much higher.
Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!
