Introduction
This manual provides instructions for the installation, operation, and maintenance of the Orbit 57101 1-Inch FPT Auto Inline Sprinkler Valve. This valve is designed to manage water flow in an automatic irrigation system, featuring a mechanism to prevent continuous water flow from a ruptured diaphragm, thereby reducing water waste and potential flooding. It also includes a manual on/off bypass lever for system testing and line flushing.
Safety Information
WARNING:
- Always turn off the main water supply before installing or performing maintenance on the valve to prevent water damage or injury.
- Ensure all electrical connections for the solenoid are properly insulated and protected from moisture to prevent electrical hazards. Consult a qualified electrician if unsure.
- Do not exceed the maximum operating pressure specified for this valve.
- Wear appropriate personal protective equipment, such as gloves and eye protection, during installation and maintenance.
Package Contents
The Orbit 57101 package includes:
- One (1) Orbit 57101 1-Inch FPT Auto Inline Sprinkler Valve
Setup and Installation
- Turn Off Water Supply: Locate and turn off the main water supply to the irrigation system before beginning installation.
- Prepare Piping: Ensure the existing piping is clean and free of debris. The Orbit 57101 valve features 1-inch Female Pipe Thread (FPT) connections.
- Orient the Valve: Observe the flow arrow molded into the valve body. Install the valve so that the arrow points in the direction of water flow towards the sprinkler heads.
- Connect Piping: Apply thread sealant (e.g., PTFE tape or pipe dope) to the male pipe threads of your irrigation lines. Carefully thread the valve onto the pipes, ensuring a watertight seal. Do not overtighten.
- Wire the Solenoid: Connect the two wires from the valve's solenoid to your sprinkler controller's common wire and the appropriate zone wire. Ensure all electrical connections are secure and protected from moisture.
- Test for Leaks: Slowly turn the main water supply back on. Inspect all connections for leaks. Tighten connections as necessary.
Operating Instructions
Automatic Operation
The Orbit 57101 valve is designed for automatic operation when connected to a compatible sprinkler controller. The controller sends an electrical signal to the valve's solenoid, which opens or closes the valve to control water flow to a specific zone.
- Ensure the valve is properly wired to your sprinkler controller.
- Program your sprinkler controller according to its specific instructions to schedule watering times and durations for the zone connected to this valve.
Manual Operation (Bypass Lever)
The valve features a manual on/off bypass lever, allowing you to operate the valve manually without the sprinkler controller. This is useful for testing the system, flushing lines, or watering a specific area outside of the programmed schedule.
- To open the valve manually, locate the bypass lever (often a small handle or screw on the solenoid). Turn or lift the lever to the "ON" or "OPEN" position.
- To close the valve manually, return the bypass lever to the "OFF" or "CLOSED" position.
- Always ensure the manual lever is in the "OFF" position for automatic operation to function correctly.
Maintenance
Regular maintenance helps ensure the longevity and proper function of your Orbit 57101 valve.
- Seasonal Inspection: Before the start of each irrigation season, inspect the valve for any visible damage, cracks, or leaks.
- Diaphragm Cleaning: If the valve is not opening or closing properly, or if there is reduced flow, the diaphragm may be obstructed by debris.
- Turn off the main water supply.
- Carefully unscrew the top of the valve (bonnet) to access the diaphragm.
- Remove the diaphragm and inspect it for dirt, sand, or mineral deposits. Clean gently with water.
- Reassemble the valve, ensuring the diaphragm is correctly seated and the bonnet screws are tightened evenly to prevent leaks.
- Winterization: In freezing climates, it is crucial to properly winterize your irrigation system, including draining water from the valves, to prevent freeze damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open automatically. | No power to solenoid, faulty solenoid, manual bypass lever is open, debris in valve. | Check controller wiring and power. Test solenoid. Ensure manual bypass is closed. Clean diaphragm. |
| Valve does not close completely. | Debris under diaphragm, worn diaphragm, low water pressure. | Clean diaphragm. Replace diaphragm if worn. Check main water pressure. |
| Water leaks from valve connections. | Improperly sealed threads, cracked valve body, loose connections. | Turn off water, reapply thread sealant and retighten connections. Inspect valve body for damage. |
| Low water flow through valve. | Partially open valve, debris in valve, clogged filter (if applicable). | Ensure valve is fully open (automatically or manually). Clean diaphragm. Check for upstream filters. |
