Customized welded forged steel ball valve

Forged steel ball valve is a common type of valve

Forging can make the internal structure finer and more uniform, eliminate defects such as looseness and porosity, so its strength, toughness, and wear resistance are better than ordinary steel, and it can withstand heavy loads and complex stresses.

The main components such as spheres, valve stems, and valve bodies are manufactured using forged steel, which has high material density and strength, and can withstand high pressure and harsh working conditions.

The sealing performance between the sphere and the valve seat is good, usually using materials such as polytetrafluoroethylene as the sealing surface, which has good wear resistance and corrosion resistance, and can achieve bidirectional sealing. Control the opening and closing of the valve by rotating the sphere. There are circular through holes on the sphere. When the sphere rotates to coincide with the axis of the pipeline, the valve opens and the medium can pass smoothly; When the sphere rotates 90 ° and the through-hole is perpendicular to the pipeline axis, the valve closes, cutting off the flow of the medium.

Similar to ordinary valves, the movement of valve discs, valve cores, and other components is used to control the on/off and flow rate of fluids. But under high pressure, it is necessary to overcome greater fluid pressure to achieve the opening and closing action of the valve.

In the field of oil and gas extraction and transportation, it is used for wellhead equipment, pressure stations for long-distance pipelines, etc.

The pipeline system of high-pressure reactors, high-pressure synthesis equipment and other equipment in the chemical industry, the steam system of supercritical and ultra supercritical power generation units in the power industry, and the primary and secondary systems of nuclear power plants. Selection and Installation

When selecting, it is necessary to choose the appropriate valve type, material, and nominal diameter based on specific parameters such as working pressure, temperature, and medium.

During installation, it is necessary to strictly follow the installation instructions to ensure that the valve is installed in the correct position, firmly connected, and to avoid leakage or other malfunctions caused by improper installation.
