Introduction of ball valve:

The ball valve is mainly composed of valve body, ball, valve seat, valve stem and transmission device. The closing part of the flange ball valve is a ball. The ball rotates around the center line of the valve body to open and close the valve. The valve can be opened and closed by 90 ° rotation of the valve stem, which is used to close, distribute, adjust the flow and change the flow direction of the medium on the pipeline.

The ball valve has a wide range of pressure and diameter, but its temperature is limited by the seal ring material.

Ball valve is divided into fixed ball valve and floating ball valve in structure; In the form of seal is divided into soft seal ball valve, hard seal ball valve and soft hard double ball valve.

Advantages of stainless steel flanged ball valve:

Precision casting valve body.After the machining,the appearance of valve body is fine,no sand hole.

Solid and heavy type valve body.

Stainless steel ball.

From the raw material to the finished product,every process has strict inpection.

Each valve will be tested for pressure according to natioal stamdards.

Inventory and Quality Control

Production process

Why do valves always fail? In the whole process of design,manufacture, installation,working condition,operation and maintenance,every step should not be lax.

The valve inspection process is as follows:

1:Appearance inspection:

(1)Whether there are sand holes, cracks and other defects on the inner and outer surface of the valve body;

(2)Whether all parts of the valve are damaged, whether the valve body is marked, etc;

2:Performance test

3.Shell strength test

4.Sealing test

5.Action performance test

6.Vacuum sealing test
