Please read this manual thoroughly before use and retain it for future reference.

2. Consignes de sécurité

Avertissement: Improper installation or operation can result in property damage, injury, or death. Always follow local codes and regulations.

• Assurez-vous que l'alimentation électrique est coupée avant toute installation, câblage ou opération de maintenance.
• Installation should be performed by qualified personnel familiar with electrical and plumbing systems.
• Verify the valve's voltage rating (85-265V AC) matches your power supply.
• Do not exceed the maximum operating pressure of 1000 Pascal.
• Protect the valve from extreme temperatures and corrosive environments unless specifically rated for such conditions.

3. Produit terminéview

The U.S. Solid Motorized Ball Valve is a robust solution for automated fluid control. Key features include:

• NPT Threading: Features 1/4 inch Stainless Steel NPT threading, ensuring compatibility with standard pipe systems. This is a full port valve.
• Vol largetagGamme : Operates effectively on 85-265V AC power.
• Fonctionnement rapide : Opens or closes the valve within 3-5 seconds.
• Efficacité énergétique : Once fully open or closed, the valve consumes minimal to no power, reducing the likelihood of overheating.
• 2-Wire Automatic Return: Simple wiring for automatic return to a closed position upon power loss.
• Durabilité: Designed for a long lifespan of 80,000-100,000 cycles.
• Indice de protection IP65 : Offre une protection contre la pénétration de poussière et les jets d'eau à basse pression provenant de toutes les directions.

5. Installation

Before installation, ensure the power supply is off and the system is depressurized. This valve is designed for NPT threaded connections.

1. Préparer les fils de discussion : Apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads. Wrap the tape clockwise around the threads, ensuring full coverage.
2. Raccorder la vanne : Carefully screw the valve onto the pipe ends. Tighten securely to prevent leaks, but do not overtighten.
3. Positionnement : Ensure the valve actuator is positioned to allow for easy access for wiring and future maintenance.
4. Inspecter: After installation, visually inspect all connections for proper alignment and tightness.

6. Schéma de câblage

This valve features a 2-wire automatic return configuration. This means the valve will open when power is applied and automatically return to its closed position when power is removed.

• Connexion: Connect the two wires from the valve to your 85-265V AC power source, typically through a switch.
• Opération: When the circuit is closed (switch is ON), the valve will open and remain open. Once open, power consumption is nominal.
• Retour automatique : When the circuit is open (switch is OFF or power is lost), the valve will close. In this state, the valve is fully de-energized, consuming zero power.

7. Fonctionnement

The U.S. Solid Motorized Ball Valve operates based on the presence or absence of electrical power to its two-wire connection.

• Pour ouvrir la vanne : Apply 85-265V AC power to the valve's two wires. The internal motor will rotate the ball to the open position within 3-5 seconds. Once fully open, the motor de-energizes, and the valve remains open with minimal power consumption.
• Pour fermer la vanne : Remove the 85-265V AC power from the valve's two wires. The valve will automatically return to its fully closed position within 3-5 seconds. Once fully closed, the valve is completely de-energized.

This automatic return feature makes it suitable for applications where a default closed state is desired, especially in case of power interruption.

8. Entretien

The U.S. Solid Motorized Ball Valve is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:

• Inspection visuelle : Regularly inspect the valve and connections for any signs of leaks, corrosion, or physical damage.
• Connexions électriques : Ensure all electrical connections are secure and free from moisture or damage.
• Fonction de l'actionneur : Periodically cycle the valve (open and close) to ensure the actuator operates smoothly and fully.
• Nettoyage: Keep the exterior of the valve and actuator clean and free from debris.

For internal components, refer to qualified service personnel only.

9. Dépannage

If you encounter issues with your motorized ball valve, consider the following troubleshooting steps:

• Vanne ne s'ouvrant/ne se fermant pas :
  • Check if power is correctly supplied to the valve (for opening) or completely removed (for closing).
  • Vérifiez le voltage matches the valve's rating (85-265V AC).
  • Vérifiez le câblage pour détecter les connexions desserrées ou endommagées.
• Fuites chez Connections :
  • Ensure pipe threads were properly prepared with thread sealant (e.g., PTFE tape).
  • Check if connections are tightened sufficiently. Do not overtighten, as this can damage threads.
• Bruit inhabituel pendant le fonctionnement :
  • Ensure the valve is not obstructed internally or externally.
  • Si le bruit persiste et affecte les performances, contactez le service client.

If these steps do not resolve the issue, please contact U.S. Solid customer support.
