Product features

The electric O type cut-off ball valve (electric on-off ball valve) is a common on-off control shut-off valve, that is, the working mode is fully open or fully closed in the two position state. Since the valve core of the ball valve uses an O type structure, Gu is called an electric O type cut-off ball valve. The electric switch ball valve can complete the switch action only by connecting the 220VAC power supply. It is especially suitable for the pipeline with large pressure difference and other fast switches and disconnects. The electric cut-off ball valve can be equipped with explosion-proof or fast switch actuators according to the working conditions and operating environment, fully meeting the needs of various process parameters.

Electric cut-off ball valve characteristic:
 
1. The electric cut-off ball valve can be opened and closed quickly with its switch in place.
2. It is easy to operate. It only needs to rotate 90 degrees from full open to full close, which is convenient for remote control.
3. The flow capacity is large, and there is basically no flow resistance when it is fully opened.
4. The electric O type cut-off ball valve has a wide range of applicability, and different connection methods and sealing rings of different materials can be selected to meet different operating conditions.
5. It has a good self-cleaning function, which can easily cut off various impurities in the pipeline and effectively ensure the smoothness of the pipeline.

Electric cut-off ball valve Difference from electric regulating ball valve:
 
1、 The electric switch ball valve is suitable for connecting or cutting off the medium in the pipeline. Only the full open and full close positions can be controlled, and the medium flow cannot be directly adjusted in proportion.
 
2、 The electric regulating ball valve can control the rotation angle of the ball valve core (that is, the size of the valve opening) to achieve different proportions, and can precisely regulate and control the flow, pressure, temperature and other parameters of the medium in the pipeline.
