Russia standard carbon steel material PN 1.6mpa flange end Floating Ball Valve

Introduction

Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Ball valve is a new type of valve widely used in recent years. It has the following advantages:

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

2. Simple structure, small volume and light weight.

3. Tight and reliable. At present, plastic is widely used as the sealing surface material of ball valve, with good sealing performance, and has 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 the disassembly and replacement are relatively convenient.

6. When fully open or fully closed, the sealing surface of the ball and valve seat shall be 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.
