3.2개의 구성요소
The U.S. Solid Motorized Ball Valve consists of two primary components: the stainless steel ball valve body and the motorized actuator unit. The actuator houses the motor, gearing, and control electronics.

4. 설정 및 설치
4.1 기계 설치
- 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.
- 밸브는 향후 유지보수를 위해 접근하기 쉬운 위치에 설치해야 합니다.

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.
- 직류 전원용: 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. 운영
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.
- 밸브를 닫으려면: 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.
- 밸브를 열려면: 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. 유지관리
The U.S. Solid Motorized Ball Valve is designed for minimal maintenance. Regular inspection can help ensure long-term reliable operation.
- 정기 검사: Visually inspect the valve and actuator for any signs of damage, corrosion, or leaks. Check electrical connections for tightness and integrity.
- 청소: 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.
- 액추에이터 점검: Periodically cycle the valve (open and close) to ensure smooth operation. Listen for any unusual noises during actuation.
7. 문제 해결
If you encounter issues with your motorized ball valve, refer to the following troubleshooting guide:
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| Valve does not actuate (open/close) | 전원이 없거나 볼륨이 올바르지 않음tage 느슨한 배선 연결 모터 고장 | 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 | 밸브 폐쇄 전력이 부족합니다 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. |
| 밸브 누출 | 나사산이 제대로 밀봉되지 않았습니다. 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. |
| 액추에이터에서 이상한 소음이 납니다. | Internal gear wear or damage | This may indicate internal wear. Monitor operation; if performance degrades, consider replacement. |
