Hunter ACCU-SYNC-ADJ Adjustable Pressure Regulator for Hunter Valve
Only Accu-Sync? adjustable model brings adjustable pressure regulation to any Hunter valve. The adjustable Accu-Sync enables the zone pressure to be customized from 20 to 100 PSI. All zones stay in tune with Accu-Sync.
Features / Benefits
- Conservation Consistent pressure regulation means no more wasted water.
- Ease Regulate pressure at the valve instead of individual sprinkler heads.
- Speed No tools are needed for the fastest installation in the industry.
- Regulation from 20 to 100 PSI (1.4 to 6.9 bar)
- Static pressure: 150 PSI
- Height with solenoid: 3-1/4"
- Length: 4-1/2"
- Required static dynamic differential: 15 PSI
- Works with AC and DC latching solenoids
- Works with any Hunter valve
For Fixed Pressure Installation
- Remove solenoid from valve
- Install solenoid in Accu-Sync
- Install Accu-Sync in valve
- Adjust to desired pressure

Then screw the solenoid into the regulator, all the way in until it 'locks' into place. You may need to hold the square part of the regulator to screw it all the way in.
If you have done this correctly then the solenoid will seem to be 'one piece' with the screws on the bottom of the regulator. (if you turn the solenoid while holding the regulator part still, the regulator threads (the male threads that screw into the valve housing) will move as if they are attached to the solenoid, and the regulator will be moveable (around the long axis of the solenoid) independent of movement of the solenoid.
So, when the 'adjuster' "runs into the valve", all you need to do is rotate it back counterclockwise, out of the way and continue to screw the solenoid-and-regulator-assembly into the hole the solenoid was originally screwed into.
The regulator body rotates freely in either direction, but only when the solenoid is completely screwed into the regulator, which is the first step after the solenoid was removed ( the "screw the solenoid into the regulator, all the way in until it 'locks' into place" step)
I have used the Accu Sync regulators in several applications and did not have good luck with them. I think the design of such a regulator has very limited applications since it is used in series with the solenoid. In my experience with the Accu Sync valves, they oscillated causing a lot of noise pipe vibration. Hunter technical support tried to address these situations, but they were never completely resolved. If you want to reduce the pressure for all zones in your sprinkler system, I would recommend installing a brass regulator at the supply. If you want to reduce the pressure for only one zone (for drip irrigation or other application) I would recommend one of the plastic inline regulators (Hunter, Rain Bird, DIG, etc...).
