1. Introduction
This motorized brass ball valve is designed for automatic control of water circulation systems in HVAC, fan coil units, solar heating systems, and other fluid control applications. The actuator provides electric on/off control through a three-wire two-way control mode. The valve body is made of brass and is suitable for cold water, hot water, and water-glycol mixtures up to 50% ethylene glycol concentration. The actuator housing is rated IP65 for protection against dust and water ingress.

3. Setup
3.1. Preparation
- Ensure the selected valve model matches the pipeline diameter and voltage supply.
- Verify that the power supply corresponds to the rated voltage indicated on the actuator label.
- Check that the pipeline is clean and free from debris before installation.
3.2. Installation
- Install the valve in the correct flow direction as marked on the valve body.
- Use appropriate sealing materials for threaded connections.
- Do not apply excessive torque to avoid damaging the brass body.
- Ensure the actuator is mounted in a dry and ventilated position.
3.3. Electrical Connection
Connect wiring according to the three-wire control diagram provided on the actuator label. Ensure power is disconnected before wiring. Confirm correct voltage before energizing the system.

4. Operation
4.1. Basic Operation
After wiring, switch on the power supply. The actuator will drive the valve to open or close within 5 to 15 seconds. Power is consumed only during movement. Verify proper flow control after installation.
4.2. Data Reading
Valve position can be confirmed by system flow status or actuator indicator if available. Detailed indicator specifications should be provided by the seller if applicable.
5. Maintenance and Storage
- Store the product in a dry, ventilated environment away from direct sunlight.
- Avoid exposure to corrosive gases or excessive humidity.
- Periodically inspect threaded connections for leakage.
- If not used for an extended period, operate the valve periodically to prevent internal sticking.
- Clean the exterior with a dry or slightly damp cloth. Do not use aggressive chemical cleaners.
6. Troubleshooting
While this product is designed for reliable operation, here are some common issues and their potential causes:
- Valve not operating: Check power supply and wiring connections. Ensure the operating voltage strictly matches the actuator rating.
- Leakage: Inspect threaded connections and ensure appropriate sealing materials were used during installation.
- Valve sticking: If unused for extended periods, internal components may stick. Operate the valve periodically to prevent this.
- System damage: Ensure nominal pressure and maximum differential pressure limits are not exceeded. Install appropriate pressure protection devices if necessary.
7. Precautions and Safety Warnings
- Ensure the operating voltage strictly matches the actuator rating.
- Do not exceed the nominal pressure of 1.6 MPa.
- Do not exceed the maximum differential pressure of 1.0 MPa.
- Medium temperature must remain within 2°C to 95°C.
- The valve is not suitable for corrosive or flammable media unless compatibility is verified.
- Disconnect power before maintenance or inspection.
- Installation and wiring must be performed by qualified personnel.
- Avoid mechanical impact to the actuator housing.
- Do not immerse the actuator in water despite IP65 protection.
7.1. General Warnings (EU Market Reference)
WARNING!
- Risk of electric shock. Disconnect power supply before installation or servicing.
- Risk of burns. The valve body may become hot during operation with high-temperature media.
- Risk of system damage due to overpressure. Install appropriate pressure protection devices in the pipeline.
- Ensure proper grounding for AC 220 V models.
- Keep out of reach of children.
- Proper disposal: Follow WEEE directives for electronic waste.
