2. معلومات السلامة
- Ensure power is disconnected before installation or maintenance to prevent electrical shock.
- تحقق المجلدtage 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.

المميزات الرئيسية:
- 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.
- حجم واسعtagالنطاق الإلكتروني: Operates effectively with 9V-24V AC/DC power.
- التشغيل السريع: 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.
- آمنة وموثوقة: Constructed from Stainless Steel 304 with NSF certification, ensuring safety for drinking water. Estimated life expectancy of 80,000 to 100,000 cycles.
عناصر:
- 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. الإعداد والتثبيت
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. تعليمات التشغيل
عملية تلقائية:
- ل يفتح 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.
- ل يغلق the valve: Remove power from the two wires. The valve will automatically rotate to the fully closed position.

التجاوز اليدوي:
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. الصيانة
- Regularly inspect the valve and connections for any signs of leaks or damage.
- Keep the actuator free from excessive dust or debris.
- التأكد من أن التوصيلات الكهربائية آمنة وخالية من التآكل.
- No internal lubrication or maintenance is typically required for the valve body or actuator.
