The electric straight through O-type cut-off ball valve has excellent cut-off performance. When the valve is fully opened, its flow path and pipeline inner diameter are basically the same, with minimal pressure loss. Its characteristics are good sealing performance, unlimited flow direction, flexible action, easy maintenance, long service life, and the same diameter valve has the highest flow capacity. It is a rotary automatic operation valve that receives switch signals and can achieve full opening or closing of the valve by rotating only 1/4 circle. It is suitable for various liquids, gases, fluids containing fibers, and small particle slurries.

There are two design structures for O-type ball valves, floating ball valves and fixed ball valves. Floating ball valves are cheaper and are more commonly found in low-pressure small-diameter valves. Fixed ball valves will not move towards the valve seat due to pressure, resulting in less pressure on the valve seat, lower torque, and longer lifespan& nbsp;< br/>

Widely applicable to production process control in industrial sectors such as petrochemicals, metallurgy, electricity, light industry, and pharmaceuticals.

Product Features

It has a compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries.

1. The fluid resistance is small, and full bore ball valves have almost no flow resistance.

2. Simple structure, small size, and light weight.

3. Tight and reliable. It has two sealing surfaces, and currently, various plastics are widely used as sealing surface materials for ball valves, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.

When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

Due to the wiping property of ball valves during opening and closing, they can be used in media with suspended solid particles.
