Product features

The electric V-shaped ball valve is a high-performance V-shaped regulating valve with a V-shaped ball core structure. Its V-shaped opening can form various V-shaped angles with the valve seat flow channel, realizing the proportional and accurate adjustment of various parameters of the pipeline medium. When the electric V-shaped regulating ball valve is closed, the V-shaped notch can easily cut off various pulp or fiber and other viscous media in the pipeline, effectively ensuring the flow of the pipeline, and preventing the ball valve core from being stuck. The electric V-shaped ball valve has approximately equal percentage or linear flow characteristics for regulating flow. The angle of the V-shaped port can be customized to meet more precise cutoff characteristics and control functions.
Advantages of electric V-ball valve: [Dynamic diagram of working principle of electric V-type ball valve]
1. The V-notch core of the electric V-type ball valve and the metal valve seat have excellent shearing function, which is especially suitable for automatic adjustment and cut-off control in industrial pipelines containing fibrous fluid, small solid particles, slurry fluid and other media.
2. The electric V-type regulating valve has a wide adjustable range, approximate equal percentage or linear flow characteristics, and reliable positioning capability.
3. The unique V-shaped valve core structure of the electric V-shaped regulating ball valve improves the controllability of the traditional ball valve, making the medium flow more precisely controlled through the opening between the V-shaped valve core openings.
