The manual integrated duplex ball valve is a special valve mainly used to control the flow of medium (such as gas, liquid, etc.) in pipelines. It consists of two independent ball valves controlled by a drive mechanism. This valve has both manual and automatic control methods, and can be selected and used according to needs.


Duplex ball valve Here's how it works:

  1. When the two ball valves are closed, the valve can completely cut off the flow of the medium, acting as a shut-off.

  2. By controlling the drive mechanism, any ball valve can be opened or closed individually or simultaneously to achieve control of the medium flow direction.

  3. Under the automatic control mode, the duplex ball valve can be automatically adjusted and controlled through cooperation with sensors, controllers and other equipment. For example, when parameters such as pressure and flow rate in the pipeline change, the duplex ball valve can automatically adjust the opening of the ball valve according to the signal of the sensor to maintain the stable flow of the medium in the pipeline.

  4. Since the duplex ball valve has two independent spheres, even if one of them fails or is damaged, the other can still function normally, improving the reliability and safety of the valve.

The manual integrated duplex ball valve is a powerful, safe and reliable valve that is widely used in various industrial pipelines, equipment and automation systems.
