4. Setup and Installation
Proper installation is crucial for the optimal performance of your PGV101G valve. Follow these general guidelines:
- Prepare the Site: Excavate the area where the valve will be installed, ensuring enough space for connections and future maintenance.
- Turn Off Water Supply: Locate and turn off the main water supply to the irrigation system.
- Connect Piping:
- Identify the inlet and outlet ports on the valve. The PGV101G typically has 1-inch NPT (National Pipe Taper) threads or barb connections.
- Apply thread sealant (e.g., PTFE tape) to all threaded connections to ensure a watertight seal.
- Connect the incoming water line to the inlet and the outgoing zone line to the outlet. Ensure connections are tight but do not overtighten.
- Electrical Connections:
- Connect the two wires from the valve's solenoid to the appropriate wires from your irrigation controller. One wire is typically common, and the other is for the specific zone.
- Use waterproof connectors (e.g., grease-filled wire nuts) to protect electrical connections from moisture.
- Ensure all connections are secure and insulated.
- Test the System:
- Slowly turn on the main water supply.
- Check for any leaks at the valve connections.
- Manually activate the valve or use the irrigation controller to test its operation.
- Backfill: Once tested and confirmed to be working correctly, carefully backfill the trench, ensuring the valve is accessible for future maintenance.
5. Operating Instructions
Manual Operation:
- To Open Manually: Turn the solenoid counter-clockwise approximately one-quarter to one-half turn. Water will begin to flow.
- To Close Manually: Turn the solenoid clockwise until it is finger-tight. Water flow will stop. Do not overtighten.
Flow Control Adjustment:
The PGV101G features a flow control knob located on top of the valve. This allows you to fine-tune the water flow for a specific zone.
- To Increase Flow: Turn the flow control knob counter-clockwise.
- To Decrease Flow: Turn the flow control knob clockwise.
- Adjust the flow control while the zone is active to achieve the desired sprinkler performance and prevent misting or excessive runoff.
Automatic Operation:
For automatic operation, the valve must be connected to an irrigation controller. Refer to your irrigation controller's manual for programming and scheduling instructions.
6. Maintenance
Regular maintenance ensures the longevity and proper function of your Hunter PGV101G valve.
- Seasonal Inspection: Before the irrigation season begins, inspect the valve for any visible damage, leaks, or debris.
- Diaphragm Check: If the valve is not operating correctly, the diaphragm may need inspection or replacement. Turn off the water, unscrew the top of the valve, and carefully examine the diaphragm for tears or blockages.
- Solenoid Check: Ensure the solenoid is securely attached and its wires are intact.
- Winterization: In freezing climates, it is essential to properly winterize your irrigation system, including the valves, to prevent freeze damage. This typically involves shutting off the water supply and draining the system. Consult a local irrigation professional if unsure.
- Cleaning: Periodically clean any debris from around the valve to ensure proper drainage and access.
