The ball valve makes the valve unblocked or blocked by rotating the valve core, and the stainless steel ball valve applies this principle, which can be closed tightly only by rotating 90 degrees with small rotating torque, and is widely used because of its characteristics of simple operation, small size, light switch and, most importantly, not easy to be corroded by media. Today, I will discuss the model, quotation and selection steps of stainless steel ball valve with Bian Xiao.

Selection steps of valves

1. Define the purpose of the valve in the equipment or device, and determine the working conditions of the valve: applicable medium, working pressure, working temperature, etc.

2. Determine the nominal diameter and connection mode of the pipeline connected with the valve: flange, thread, welding, etc.

3. Determine the operation mode of the valve: manual, electric, electromagnetic, pneumatic or hydraulic, electric or electro-hydraulic linkage, etc.

4. According to the medium transported by the pipeline, working pressure and working temperature, the materials of the shell and internal parts of the selected valve are determined: gray cast iron, malleable cast iron, nodular cast iron, carbon steel, alloy steel, stainless and acid-resistant steel, copper alloy, etc.

5. Determine the types of valves: gate valves, globe valves, ball valves, butterfly valves, throttle valves, safety valves, pressure reducing valves, steam traps, etc.

6. Determine the parameters of the valve: For automatic valves, first determine the allowable flow resistance, discharge capacity, back pressure, etc. According to different needs, determine the nominal diameter of the pipeline and the diameter of the valve seat hole.

7. Determine the geometric parameters of the selected valve: structural length, flange connection form and size, height size of the valve after opening and closing, size and number of connecting bolt holes, and overall size of the valve.

8. Use existing materials: valve product catalogue, valve product samples, etc. Select the appropriate valve products.

Summary: The above is a complete collection of stainless steel ball valve models and a detailed description of the valve purchase steps, hoping to help you. Stainless steel ball valve is very easy to connect with other metal iron products, and it will rust after long-term contact. If you want it not to rust, try to pack it in wooden cases during transportation to avoid touching metal products; Or after the finished product is finished, water with antirust powder is added for cleaning. In addition, it should be maintained at ordinary times, such as lubricating the valve stem.
