5. Installation
Before installation, ensure the power supply is off and the system is depressurized. This valve is designed for NPT threaded connections.
- Prepare Threads: Apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads. Wrap the tape clockwise around the threads, ensuring full coverage.
- Connect Valve: Carefully screw the valve onto the pipe ends. Tighten securely to prevent leaks, but do not overtighten.
- Positioning: Ensure the valve actuator is positioned to allow for easy access for wiring and future maintenance.
- Inspect: After installation, visually inspect all connections for proper alignment and tightness.

6. Wiring Diagram
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.
- Connection: Connect the two wires from the valve to your 85-265V AC power source, typically through a switch.
- Operation: When the circuit is closed (switch is ON), the valve will open and remain open. Once open, power consumption is nominal.
- Automatic Return: 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. Operation
The U.S. Solid Motorized Ball Valve operates based on the presence or absence of electrical power to its two-wire connection.
- To Open the Valve: 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.
- To Close the Valve: 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. Maintenance
The U.S. Solid Motorized Ball Valve is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- Visual Inspection: Regularly inspect the valve and connections for any signs of leaks, corrosion, or physical damage.
- Electrical Connections: Ensure all electrical connections are secure and free from moisture or damage.
- Actuator Function: Periodically cycle the valve (open and close) to ensure the actuator operates smoothly and fully.
- Cleaning: Keep the exterior of the valve and actuator clean and free from debris.
For internal components, refer to qualified service personnel only.
9. Troubleshooting
If you encounter issues with your motorized ball valve, consider the following troubleshooting steps:
- Valve Not Opening/Closing:
- Check if power is correctly supplied to the valve (for opening) or completely removed (for closing).
- Verify the voltage matches the valve's rating (85-265V AC).
- Inspect wiring for loose connections or damage.
- Leaks at 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.
- Unusual Noise During Operation:
- Ensure the valve is not obstructed internally or externally.
- If the noise persists and affects performance, contact customer support.
If these steps do not resolve the issue, please contact U.S. Solid customer support.
