Ball valves are very good at maintaining and regulating high volumes, high pressures and high flow rates, so they are suitable for many different types of applications.

The spherical valve is also durable and provides a lot of reliable services, and will not fail or malfunction. One of the types.
In addition, ball valves will also become one of the leading automobile types in large and medium-sized calibers and low- and medium-pressure fields in other industries.

* Has the lowest flow resistance (actually).
* Because it will not get stuck when there is no work), it can be reliably applied and opened in liquids with low boiling points.
* In the possible range of ground pressure and temperature, a complete seal can be achieved.
* It can realize fast opening and closing, and the opening and closing time of some structures can be automatically system 0.05~0.1s to ensure that it is used in the test bench. Quick opening and closing, no impact on operation.
* The ball closure can be automatically positioned in position.
* The working media is reliable on both sides.
* When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the isolation, so there will be no leakage of the sealing surface through the interface of the car at high speed.
* The structure and weight are light, and it can be considered as the most reasonable vaporization structure of the cryogenic medium system.
* The body of the valve body, especially the welded valve body structure, can well reduce the breathing of diseases.
* The high pressure difference when the closure can be closed.

* The fully welded ball valve can be buried in the ground, so that the internal parts of the cylinder are buried and leaked. The longest service life, 3 years of service life, is the most natural gas for oil and natural ideal gas.

Trunnion ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and harsh environment resistance have been specially considered in the design, and it is suitable for various corrosive and non-corrosive media. Compared with the floating ball valve, when working, the force generated by the fluid pressure is transmitted to the bearing on the ball of the previous ball valve, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure.

铸件 缺陷一直是困扰铸造企业的一大难题。铸件缺陷的不良解决方案会影响铸件的质量。各种铸件在生产机床铸件过程中出现的磨损、划痕、砂孔、针孔、裂纹、缺陷和变形、硬度降低、损坏等缺陷。目前市场上采用焊补修复缺陷，一般有以下几种： 一、氩弧焊：精密铸件（合金钢、不锈钢精密铸件）、铝合金压铸件多采用氩弧焊焊接机器。一些模具制造和维修制造商也使用这种焊机来修复模具缺陷。

After we provide some batches machined ball valve components successfully to our Korea client, now we are requested to supply more, which is beyond we expected. The new components are 200 pcs adapter plate for trunnion ball valve. The material is forged ASTM A105N with ENP coated.

In this case, our engineer took part in the design stage and help client to find way to save cost, enhance products property, the whole machining process is quite normal for us.
Now we are quite confident to handle any complex ball valve components at client’s requirements.
