Two piece forged steel ball valve is a common pipeline valve that has been widely used in the industrial field due to its structural characteristics and performance. This type of valve is mainly composed of two valve bodies, which are connected together by bolts and have the advantages of easy installation and maintenance. Due to the use of forged steel structure material, this type of valves has high strength and corrosion resistance, making it suitable for use in harsh working conditions such as high temperature and high pressure
Structural characteristics
The core of the two-piece forged steel ball valves lies in its two-piece design, which allows the valve to be easily disassembled and assembled, greatly simplifying the process of maintenance and replacement. The valve body is usually manufactured using forging technology to ensure the strength and durability of the product. The sealing surface is generally made of plastic material, such as PTFE, which provides good sealing performance and can also be applied in vacuum systems.
Usage performance
The operation of the two-piece forged steel ball valve is very convenient, only requiring a 90 ° rotation to complete the action from fully open to fully closed, suitable for remote control. It has low fluid resistance and hardly affects the flow of the medium. In addition, due to the isolation of the ball and valve seat from the medium when fully open or fully closed, it will not cause erosion of the sealing surface, thereby extending the service life of the valve.
Compared to globe valves
The opening and closing component of a ball valve is a perforated sphere that can rotate around the centerline of the valve body, achieving opening and closing by rotating 90 degrees. Ball valves have good sealing performance, simple operation, and are suitable for occasions that require frequent opening and closing. The opening and closing member of the globe valve is a plug shaped valve disc, which moves along the centerline of the fluid and controls the position of the valve disc through the lifting and lowering of the pvc globe valve stem, thereby controlling the flow rate of the medium. Globe valves are suitable for applications that require precise flow control, such as throttling and pressure regulation.
