1. Preparation of materials:
The main materials of ball valves are stainless steel, cast iron, chromium-molybdenum steel, etc. These materials need to be processed and treated to ensure that their quality meets the requirements.
2. Processing spheres:
The ball of the ball valve is the core part of it, and its processing needs to be carried out by high-precision equipment such as CNC machine tools to ensure the accuracy and surface finish of the ball.
3. Cast valve body:
The valve body of the ball valve needs to be cast according to the design drawings, and it also needs to be processed and polished.
Fourth, install the valve stem:
The stem is the control part of the ball valve and needs to be installed and adjusted to ensure smooth stem movement.
5. Install the gasket:
Ball valves require gaskets for sealing, which requires installation and adjustment to ensure their sealing performance.
6. Testing:
After the manufacture of the ball valve is completed, it is necessary to carry out pressure test, withstand pressure test and other testing work to ensure that its performance and quality meet the requirements.
7. Packing:
Ball valves need to be packaged and labeled after manufacturing, and have quality proof to ensure their safe transportation and use.
