Product details

PRODUCT OVERVIEW

The working principle of Japanese standard pneumatic high platform ball valve in the pipeline is to smooth or block the valve by rotating the valve stem. It is mainly used for fast cutting speed, distribution and changing the flow direction of medium. It has many advantages, such as sensitive action, good sealing performance and so on. The sealing surface and spherical surface are often in the closed state and are not easy to be eroded by the medium. They are widely used in various industries. It is widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other fields, as well as people's daily life.

PRODUCT FEATURES

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.

2. The utility model has the advantages of simple structure, small volume and light weight.

3. It is tight and reliable. At present, plastic is widely used as the sealing surface material of ball valve, with good sealing performance. It has also been widely used in vacuum system.

4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.

5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

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

7. It has a wide range of applications, ranging from small to several millimeters and large to several meters. It can be applied from high vacuum to high pressure.
