5. Pengaturan dan Instalasi
Proper installation is crucial for the valve's performance and longevity.
5.1 Instalasi Mekanik
- Prepare Pipe Ends: Ensure pipe ends are clean and free of debris.
- Aplikasikan Sealant: For NPT threads, apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads to ensure a watertight seal.
- Thread Valve: Carefully thread the valve onto the pipe. Tighten firmly but do not overtighten, which can damage threads or the valve body.
- Orientasi: The valve can be installed in any orientation, but ensure the actuator is accessible for wiring and inspection.

5.2 Electrical Wiring (2-Wire Auto Return)
This valve features a 2-wire auto return setup. It is a normally open valve, meaning it is open when no power is applied. Applying power will close the valve, and removing power will cause it to return to the open position.
- Sumber Daya: Connect the valve to a 9-24V AC or DC power source.
- Pengkabelan: Connect the two wires from the valve to your power source. The valve will operate regardless of polarity for DC connections.
- Operasi: When power is applied, the valve will move to the closed position. When power is removed, the valve will automatically return to the open position.

6. Petunjuk Pengoperasian
The U.S. Solid Motorized Ball Valve is designed for straightforward operation based on its 2-wire auto return, normally open configuration.
- Normally Open State: When no electrical power is supplied to the valve, it remains in the fully open position, allowing fluid to flow through.
- Closing the Valve: To close the valve, apply 9-24V AC/DC power to the two wires. The internal motor will actuate the ball, moving it to the closed position within 3-5 seconds. Once fully closed, the internal limit switch will cut power to the motor, preventing overheating.
- Opening the Valve (Auto Return): To open the valve, simply remove the electrical power supply. The valve's auto return mechanism will automatically move the ball back to the fully open position.

7. Pemeliharaan
The U.S. Solid Motorized Ball Valve is designed for minimal maintenance. However, periodic checks can help ensure optimal performance.
- Inspeksi Visual: Regularly inspect the valve for any signs of leaks, corrosion, or physical damage to the valve body or actuator housing.
- Sambungan Listrik: Pastikan semua sambungan listrik aman dan bebas dari korosi.
- Actuator Function: Periodically cycle the valve (open and close) to confirm smooth operation and proper response to power signals.
- Pembersihan: Keep the exterior of the actuator clean and free of excessive dust or debris. The IP65 rating provides protection against dust and water jets, but harsh chemicals should be avoided.
- Tidak Ada Bagian yang Dapat Diservis Pengguna: The actuator mechanism contains no user-serviceable parts. Do not attempt to disassemble the actuator, as this will void any warranty and may cause damage.
8. Penyelesaian masalah
If you encounter issues with your motorized ball valve, refer to the following troubleshooting guide:
| Masalah | Kemungkinan Penyebab | Larutan |
|---|---|---|
| Katup tidak terbuka/tertutup | Tidak ada daya atau vol yang salahtage. | Verify power supply is connected and within the 9-24V AC/DC range. Check wiring for loose connections. |
| Valve does not open/close fully | Obstruction in the flow path or internal mechanism. | Ensure no debris is blocking the ball. If the issue persists, the valve may require replacement. |
| Kebocoran katup | Improperly sealed threads or damaged valve body/seals. | Check thread sealant application. If the leak is from the valve body or stem, the valve may be damaged and require replacement. |
| Actuator makes noise but valve doesn't move | Internal gear damage or motor issue. | This indicates an internal mechanical failure. The actuator is not user-serviceable; valve replacement is recommended. |
| Valve overheats | Continuous power supply after reaching end position (limit switch failure). | Disconnect power immediately. This valve is designed to cut power via a limit switch. If overheating occurs, the limit switch may be faulty, and the valve should be replaced. |
