4. Konfigurazioa eta instalazioa
4.1 Instalazio mekanikoa
- Ensure the system is depressurized and drained before installation.
- Apply PTFE (Teflon) tape to the male pipe threads to ensure a watertight seal. Wrap the tape clockwise around the threads, typically 3-5 layers.
- Screw the valve firmly into the piping system. Do not overtighten, as this can damage the threads or valve body.

4.2 Electrical Wiring (2-Wire Auto Return Setup)
This valve features a 2-wire auto return setup, meaning it will return to its fully open position if power is removed. It is a Normally Open (NO) valve, which means it is open when no power is applied.
- For DC Power: Connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal of your 9-24V DC power supply. Applying power will close the valve. Removing power will cause the valve to automatically return to its open position.
- For AC Power: Connect the red wire to one AC line and the black wire to the other AC line of your 9-24V AC power supply. Applying power will close the valve. Removing power will cause the valve to automatically return to its open position.

5. Funtzionamendua
The U.S. Solid Motorized Ball Valve is designed for simple on/off control. As a Normally Open (NO) valve, its default state without power is open.
- Balbula ixteko: Apply 9-24V AC/DC power to the red and black wires. The actuator will rotate, closing the ball valve. Once fully closed, an internal limit switch will cut power to the motor, preventing overheating.
- Balbula irekitzeko: Remove the 9-24V AC/DC power from the red and black wires. The actuator will automatically return to its original position, opening the ball valve.

6. Mantentzea
The U.S. Solid Motorized Ball Valve is designed for minimal maintenance. Regular inspection can help ensure long-term reliable operation.
- Aldizkako ikuskapena: Visually inspect the valve and actuator for any signs of damage, corrosion, or leaks. Check electrical connections for tightness and integrity.
- Garbiketa: If necessary, clean the exterior of the valve and actuator with a damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no water enters the actuator housing.
- Aktuadorearen egiaztapena: Periodically cycle the valve (open and close) to ensure smooth operation. Listen for any unusual noises during actuation.
7. Arazoak
If you encounter issues with your motorized ball valve, refer to the following troubleshooting guide:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| Valve does not actuate (open/close) | Potentziarik ez edo bolumen okerratage Kableatu konexio soltea Motorra matxura | Verify power supply (9-24V AC/DC) and connections. Check for secure wiring. Ensure correct polarity for DC. If power is present and connections are secure, the motor may be faulty. Contact support. |
| Valve does not fully open or close | Obstruction in valve Potentzia nahikoa ez Internal gear damage (as noted in some user experiences) | Inspect the valve for debris. Ensure adequate power supply. If the issue persists, the internal mechanism may be damaged. Contact support. |
| Balbula ihesak | Gaizki zigilatutako hariak Damaged valve body or seals | Ensure PTFE tape was applied correctly and connections are tight. If the leak is from the valve body itself, the valve may be damaged and require replacement. |
| Actuator makes unusual noise | Internal gear wear or damage | This may indicate internal wear. Monitor operation; if performance degrades, consider replacement. |
