4. Persediaan dan Pemasangan

4.1 Pemasangan Mekanikal

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.

Figure 6: Illustration of applying Teflon tape to male pipe threads for a secure, leak-free connection.

Screw the valve firmly into the piping system. Do not overtighten, as this can damage the threads or valve body.
Ensure the valve is installed in an accessible location for future maintenance.

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.

Untuk Kuasa DC: 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.
Untuk Kuasa AC: 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. Operasi

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.

Untuk Menutup Injap: 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.
Untuk Membuka Injap: 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. Penyelenggaraan

The U.S. Solid Motorized Ball Valve is designed for minimal maintenance. Regular inspection can help ensure long-term reliable operation.

Pemeriksaan Berkala: Visually inspect the valve and actuator for any signs of damage, corrosion, or leaks. Check electrical connections for tightness and integrity.
Pembersihan: 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.
Pemeriksaan Penggerak: Periodically cycle the valve (open and close) to ensure smooth operation. Listen for any unusual noises during actuation.

7. Penyelesaian masalah

If you encounter issues with your motorized ball valve, refer to the following troubleshooting guide:

Masalah	Kemungkinan Punca	Penyelesaian
Valve does not actuate (open/close)	Tiada kuasa atau vol tidak betultage Sambungan pendawaian longgar Kerosakan motor	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	Obstruction in valve Kuasa tidak mencukupi 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.
Injap bocor	Benang yang tidak dimeterai dengan betul 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.
Actuator makes unusual noise	Internal gear wear or damage	This may indicate internal wear. Monitor operation; if performance degrades, consider replacement.
