DIN Standard PN16 2PS Cast Iron Flang End Floating Ball Valve

Introduction

Ball valve and gate valve belong to the same type of valve. The difference is that its closing part is a ball. The ball rotates around the center line of the valve body to open and close. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Flange ball valve standard GB / t21465-2008 "valve terminology" is defined as a valve in which the hoist (ball) is driven by the valve stem and rotates around the axis of the valve stem.

Feature

Advantages

Ball valve is a new type of valve widely used, which 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. It is tight and reliable. 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 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. This type of valve shall be installed horizontally in the pipeline
