3-way Flanged Ball Valve Material Description

3 Way Flanged Ball Valve Material Description and Application: 3 Way Flanged Ball Valve is widely used in a wide range of industries, and its operating principle is relatively simple. Most valves require a medium to operate. Furthermore, the vast majority of valves employ a forced seal. This means that when the valve is closed, an external force is applied to press the gate against the valve seat to ensure a tight seal.

Material Description for 3 Way Flanged Ball Valve
1. For valve stems, stainless steel (2CR13) is preferred. Large-diameter valves should also have stainless steel insert stems.
2. For nut materials, cast aluminum brass or cast aluminum bronze should be used, with a higher hardness and strength than the valve stem.
3. For valve stem bushings, the hardness and strength should not exceed that of the valve stem, and the material should not cause electrochemical corrosion with the valve stem or valve body when immersed in water. 4. 3 Way Flanged Ball Valve body materials (Jiuzhaigou tour chartered buses) should primarily be ductile iron, cast steel, stainless steel, or 316L. The brand and actual physical and chemical test data of the cast iron should be clearly stated.
5. 3 Way Flanged Ball Valve Sealing surface material
① 3 Way Flanged Ball Valve: The copper ring's material, fixing method, and grinding method should all be clearly stated.
② 3 Way Flanged Ball Valve: The physical, chemical, and hygienic test data of the valve plate lining rubber material should be clearly stated.
③ Different pneumatic valve types have different sealing method and material requirements.
④ 3 Way Flanged Ball Valve: The valve body sealing surface material should be clearly stated. Physical and chemical test data should be clearly stated, especially the rubber's hygienic requirements, aging resistance, and wear resistance. Nitrile rubber and EPDM are commonly used; the use of recycled rubber is strictly prohibited. 6. Valve Shaft Packing
① Because pneumatic valves in pipeline networks typically operate infrequently, the packing must remain stationary for several years, preventing aging and maintaining a long-term seal.
② Valve shaft packing must also maintain excellent sealing performance despite frequent opening and closing.
③ Given these requirements, valve shaft packing should be designed to last for life or over ten years.
④ If packing replacement is necessary, the design should include provisions for replacement under water pressure.

These double-disc valve designs each have their own characteristics, costs, and manufacturing processes, as well as their own advantages and disadvantages. While designs for valves with 3 Way Flanged Ball Valve valves are also becoming more diverse, there are also common patterns. Currently, commercially available valves with 3 Way Flanged Ball Valve valves can be broadly divided into two categories. One type consists of two gates and a wedge structure, which independently function to achieve a seal. The other type incorporates a wedge and gate into a single thermal storage electric boiler, with the gate itself acting as a wedge, creating a self-sealing seal. In contrast, the second type of structure offers greater stability because it requires fewer parts while maintaining similar functionality. This significantly improves stability.

The design process should also consider the potential scenarios encountered during actual use, designing an appropriate structure based on each situation. The flat plate valve studied in this project is primarily used in the petroleum industry, requiring a safe, reliable, and robust structure with excellent sealing performance.
