Introduction
Motorized ball valves are a vital piece of equipment in numerous applications. This model opens and closes in 6-8 seconds, and remains in its new position while expending almost no energy. This is a key difference between motorized ball valves and many solenoid valves. Most solenoid valves are energized continuously when in a new position, while motorized ball valves expend energy only when changing from open to close, or vice versa.
This series features a 2-wire auto-return function and is equipped with a manual function, allowing users to forcefully change the valve's state via a hand knob during power outages or system debugging, thereby offering exceptional operational flexibility and emergency security.
Applications
Features
- Normally Open: Open when unpowered, closes when energized.
- NPT / G Threading: NPT (National Pipe Taper) and G (BSPP) to accommodate diverse global specifications, ensuring a secure seal with teflon tape.
- Valve Body Material: Constructed from stainless steel. Suitable for drinking water applications.
- 9V-24V AC/DC: Works effectively over entire voltage range, this motorized ball valve will open or close valve in 6~8 seconds.
- 2 Wire Auto Return: Simple two-wire connection, automatically returning to its safe state when power is removed.
- Manual Function: Enables emergency actuation via a dedicated hand knob, ensuring the valve can be quickly opened or closed without electrical power.

FAQ
Problem 1: What is the difference between N.C. (Normally Closed) and N.O. (Normally Open)?
- Normally Closed (NC): Valve remains closed when power is off, opening only when energized. Ideal for fail-safe closed applications.
- Normally Open (NO): Valve remains open when power is off, closing only when energized. Ideal for fail-safe open applications.
Problem 2: What is the difference between Full Port and Standard Port?
- Full Port: Matches pipe diameter, minimal flow restriction, ideal for high flow and low pressure drop.
- Standard Port: Smaller than pipe diameter, higher resistance, suitable for general flow and pressure needs.
Problem 3: Can this be used for Drinking Water?
Yes. This motorized ball valve is made of stainless steel, which is safe for drinking water applications.
Problem 4: For auto return valves, what is the minimum On-Time required for electrical storage to enable closing when power off?
To ensure automatic reset functionality when the power is disconnected, it is essential to power the device for approximately one minute to charge the capacitor in 2-wire auto return motorized ball valves.
Problem 5: How to wire a 2-wire auto-return motorized ball valve?
Connect the red wire to the positive pole(+) and the black wire to the negative pole(-) to open the valve. Disconnecting either wire will close the valve.
Manual Function
Red line
The valves is fully closed when the red line on the position indicator ② points to "CLOSED"(vertical to the pipe).Likewise,the valve is fully open when it points to "OPEN"(parallel to the pipe).
Steps
- Before manual operation, ensure the valve is in a power-off state.
- First, gently pull up the handwheel. At this point, rotating it will open or close the passage. You will feel a slight lift of the rod when pulling up; if it cannot be lifted, try rotating it to adjust the position.
- Do not use excessive force. While rotating, pay attention to the red line in the indicator window to avoid over-operation.
- After completing the manual operation, press down the handwheel to ensure the normal operation of the electric function.
Precautions
- For 2-wire reverse polarity and 3-wire models, the valve is de-energized when fully open or closed. Other models may use a negligible amount of power when fully open, and the 5-wire model uses energy when closed to keep indicator lights operational. Refer to the specifications sheet for detailed information.
- Only Auto Return Models will return to the closed position in the event of a power outage. All other models will remain in their current position. If this is a concern, consider purchasing an Auto-Return Model.
- These valves are designed with power-limiting features, allowing them to be powered continuously without risk of overheating. However, always ensure proper installation and adherence to manufacturer guidelines to maintain safe operation.
