1. Kupu Whakataki

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your U.S. Solid 1/2 Inch Stainless Steel Motorized Ball Valve. This valve features a full port design, 9-24V AC/DC power compatibility, and a 2-wire auto return setup, making it suitable for various fluid control applications. Please read this manual thoroughly before use and retain it for future reference.

2. Nga korero haumaru

• Ensure all power sources are disconnected before installation or maintenance to prevent electrical shock.
• Manatokohia ko te voltage and current of your power supply match the valve's specifications (9-24V AC/DC).
• Install the valve in an environment where the ambient temperature is within the specified range (less than 40°C).
• Ensure the medium temperature flowing through the valve does not exceed 100°C.
• Do not exceed the maximum operating pressure of 1.0 MPa (10 Bars).
• Use appropriate sealing materials, such as PTFE tape, on threaded connections to prevent leaks.
• Avoid applying excessive force during installation that could damage the valve body or motor.

3. Hua Neke Atuview

3.1 Nga waahanga

• Haumaru me te Whakapono: Constructed from 304 stainless steel, offering durability and an estimated life expectancy of 80,000 to 100,000 cycles.
• NPT Threading: Features 1/2" 304SS NPT threads, ensuring compatibility with standard pipe systems.
• Full Port Design: The bore in the ball is a full 1/2", minimizing pressure loss through the valve.
• Whanui Voltage Awhe: Operates effectively with 9-24V AC/DC power supply.
• Mahi Tere: Opens or closes the valve in 3-5 seconds.
• 2-Wire Auto Return Setup: Simple two-wire connection. The valve largely de-energizes after closing and returns to fully open if power is removed.
• Alternative to Solenoid Valves: Automatically cuts off power once fully open or fully closed, reducing the likelihood of overheating.

3.2 Waehanga

The U.S. Solid Motorized Ball Valve consists of a stainless steel ball valve body and an integrated electric actuator. The actuator houses the motor, gearing, and control circuitry.

4. Tatūnga me te Tāuta

4.1 Tāuta Hangaia

1. Ensure the piping system is clean and free of debris before installing the valve.
2. Apply appropriate thread sealant (e.g., PTFE tape) to the male pipe threads.
3. Screw the valve firmly into the piping system. Do not overtighten.
4. Ensure the valve is installed in a position that allows for easy access for wiring and future maintenance.

4.2 Electrical Wiring (2-Wire Auto Return)

This valve operates with a simple 2-wire auto return mechanism. When power is applied, the valve opens. When power is removed, the valve automatically closes.

• Connect the two wires from the valve to your 9-24V AC/DC power source. The valve will open when energized.
• When the power is disconnected, the valve will automatically return to its fully closed position.
• A limit switch minimizes power consumption once the valve is fully open or closed.

5. Nga Tohutohu Whakahaere

The U.S. Solid Motorized Ball Valve is designed for straightforward operation based on power supply.

• Hei whakatuwhera i te Valve: Apply 9-24V AC/DC power to the valve's two wires. The motor will actuate, rotating the ball to the open position within 3-5 seconds. Once fully open, the internal limit switch will reduce power consumption.
• Hei Katia te Valve: Disconnect the power supply from the valve. The auto-return mechanism will engage, rotating the ball to the closed position.

6. Tiaki

Regular maintenance ensures the longevity and optimal performance of your motorized ball valve.

• Tirohanga Ia Wa: Regularly check for any signs of leakage, corrosion, or physical damage to the valve body and actuator.
• Hononga Hiko: Me whakarite kia mau nga hononga hiko katoa me te kore e waikura.
• Te horoi: Keep the exterior of the actuator clean and free from dust or debris. Do not use harsh chemicals that could damage the housing.
• Tirotiro Whakahaere: Periodically cycle the valve (open and close) to ensure smooth operation.

7. Te Raru

If you encounter issues with your U.S. Solid Motorized Ball Valve, consider the following common checks:

• Valve Not Opening/Closing:
  • Check power supply: Ensure the correct voltage (9-24V AC/DC) is being supplied and that connections are secure.
  • Inspect wiring: Verify that the wires are correctly connected according to the 2-wire auto return diagram.
  • Check for obstructions: Ensure there are no physical obstructions preventing the ball from rotating.
• Leakage:
  • Check threaded connections: Ensure NPT threads are properly sealed with PTFE tape and tightened sufficiently.
  • Inspect valve body: Look for any cracks or damage to the stainless steel body.
• Haruru rereke i te wa e mahi ana:
  • This could indicate internal wear or debris. If persistent, contact customer support.
