The GYR-51300 series O-type ball valve is a kind of right-angle return transformation cut-off valve which is also used as a regulating valve on a few occasions. It is used in conjunction with pneumatic or electric actuators to achieve remote control and can also be equipped with a handle or turbine for manual control. This type of valve is mainly used in pipelines to cut off distribute and change the flow direction of the medium. It is a new type of valve widely adopted in recent years.
The advantages:
1. Small fluid resistance and its resistance coefficient are equal to that of pipe sections of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for ball valves, with good sealing performance. It has also been widely used in vacuum systems.
4. Convenient operation, it can be quickly opened or closed with only 90° rotation from full opening to full closing, which is convenient for remote control.
5. Convenient maintenance, simple ball valve structure, and the sealing rings are generally moveable, which makes disassembly and replacement more convenient.
6. 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. Widely applicable, with diameters ranging from several millimeters to meters, and can be applied from high vacuum to high pressure.
