2. Safety Information

Ensure power is disconnected before installation or maintenance to prevent electrical shock.
Verify voltage compatibility (9-24V AC/DC) before connecting the valve to a power source.
Install the valve in an environment suitable for its IP65 rating. If used outdoors, consider additional protection from direct rain or water spray, especially around the manual override knob.
Do not exceed the maximum operating pressure of 1.0 MPa (145 PSI).
Ensure proper threading and sealing to prevent leaks.
This valve is suitable for drinking water applications due to its NSF certification and Stainless Steel 304 construction.

3. Product Overview

Key Features:

NPT Threading: 3/4" quality stainless steel thread, manufactured and measured according to National Pipe Thread standards. Full port design with a 3/4" (20mm) bore.
Wide Voltage Range: Operates effectively with 9V-24V AC/DC power.
Fast Operation: Opens or closes the valve in approximately 6-8 seconds.
2-Wire Automatic Return Setup: Simple two-wire connection. Features a limit switch that minimizes power consumption once the valve is fully open. The valve automatically returns to a fully closed position if power is removed, ideal for applications requiring automatic return.
Alternative to Solenoid Valves: Minimizes power consumption after opening, reducing the risk of overheating, making it suitable for applications where the valve needs to remain open for extended periods.
Safe and Reliable: Constructed from Stainless Steel 304 with NSF certification, ensuring safety for drinking water. Estimated life expectancy of 80,000 to 100,000 cycles.

Components:

Motorized Actuator (Blue housing)
Stainless Steel 304 Ball Valve Body
Electrical Wiring (2-wire)
Manual Override Knob (White, on top of actuator)
Visual Position Indicator (Red line, on top of actuator)

5. Setup and Installation

5.1. Mechanical Installation (NPT Threading)

Ensure the piping system is depressurized and drained before installation.
Apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads.
Screw the valve firmly into the piping system. Avoid overtightening, which can damage threads.
Ensure the valve is oriented correctly for your application, considering flow direction and actuator position.

5.2. Electrical Wiring (2-Wire Auto Return)

The U.S. Solid 2-wire auto return motorized ball valve is designed for simple on/off control. It requires a 9-24V AC/DC power source. The valve will open when power is applied and automatically close when power is removed.

Connect the two wires from the valve to your 9-24V AC/DC power source. The polarity (positive/negative) does not affect the valve's operation for opening, but consistent wiring is recommended.
When power is applied, the valve will open. A limit switch inside the actuator will minimize power consumption once the valve is fully open.
When power is removed, the valve will automatically return to its fully closed position.

6. Operating Instructions

Automatic Operation:

To open the valve: Apply 9-24V AC/DC power to the two wires. The valve will rotate to the fully open position in 6-8 seconds. Once open, power consumption is minimal.
To close the valve: Remove power from the two wires. The valve will automatically rotate to the fully closed position.

Manual Override:

In case of power failure or for manual control, the valve can be operated manually:

Locate the white manual override knob on top of the blue actuator.
Rotate the knob to manually open or close the valve. The red line indicator will show the current valve position.

7. Maintenance

Regularly inspect the valve and connections for any signs of leaks or damage.
Keep the actuator free from excessive dust or debris.
Ensure the electrical connections are secure and free from corrosion.
No internal lubrication or maintenance is typically required for the valve body or actuator.

8. Troubleshooting

Problem	Possible Cause	Solution
Valve does not open when power is applied.	No power, incorrect voltage, loose wiring, internal motor issue.	Check power supply and voltage. Verify all electrical connections are secure. Test with a known working power source. If issues persist, contact support.
Valve does not close when power is removed.	Power not fully removed, internal mechanism fault.	Ensure power is completely disconnected. Try manual override. If issues persist, contact support.
Leakage from valve connections.	Improper threading, insufficient sealant, damaged threads.	Ensure proper application of thread sealant (e.g., PTFE tape). Tighten connections appropriately. Inspect threads for damage.
Valve operates slowly or intermittently.	Low voltage, debris in valve, motor wear.	Verify power supply voltage. Flush the system to remove potential debris. If problem persists, contact support.
