Electric Three-Way Ball Valve
Product Introduction
HDQ series electric ball valves are suitable for on-off control of air conditioning fan coil systems and central heating systems. It consists of a ball valve body and an actuator, and the actuator drives the valve core to rotate 90°.
The actuator is driven by a synchronous motor with built-in limit contacts, which can cut off power supply when the valve is fully open or fully closed, ensuring stable operation. HDQ series electric ball valves are widely applied in central heating systems, time proportioning control systems, central air conditioning pipeline systems, solar energy systems and other systems.

CONNECTION MODE
The HDQ series electric ball valve is suitable for on/off control in air conditioning fan coil units and central heating systems. It consists of a ball valve and an actuator. The actuator drives the valve core to rotate 90°. The actuator is driven by a synchronous motor and features built-in limit switches that cut off power when the valve is fully open or fully closed, ensuring stable operation. The HDQ series electric ball valve is widely used in central heating systems, time-area based heating control systems, central air conditioning coil systems, solar systems, and more.

2-wire power-off close (open):
- When SW is closed, the valve opens/closes; after reaching the position, the internal power supply is automatically cut off, and the valve remains in the open/closed state. The backup power supply is charged.
- When SW is powered off, the valve closes/opens; after reaching the position, the internal power supply is automatically cut off, and the valve remains in the closed/open state.
- Note: The power-on time should not be less than 1 minute.
