New Developed Flanged Ball Valves

Brief Introduction Design characteristics of flange ball valves: The flange ball valves produced by JOEPAI valve adopts silicon melt casting or forging technology for the valve body, and adopts a floating structure.

This structure can produce a certain displacement of the ball under the pressure of the medium and press it tightly on the sealing surface of the outlet end, ensuring the sealing of the outlet end and good sealing performance. Widely used in medium and low pressure ball valves, the valves are designed with fire and anti-static properties to meet the requirements of pipeline transportation systems in the petroleum and natural gas industries.

Technical parameters: 

1. Nominal pressure or pressure level: DIN PN16-PN320, ANSI Class 150-900LB, JIS10K-20K;

2. Nominal diameter or diameter: DN15-900, NPS 1/2"~ 36";

3. Connection method: flange ends;

4. Applicable temperature: -196 ℃~300 ℃;

5. Driving methods: manual, worm gear, pneumatic and electric;

6. Valve body materials: CF8 (304), 1.4308 (304), CF3 (304L), CF8M (316), CF3M (316L), 1.4408 (316) Ti. WCB, ZG 1Cr18Ni9Ti, ZG 1Cr18Ni12Mo2Ti, By selecting different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. (the materials are tracked and detected through spectral analysis);

7. The valve stem is made of high-performance stainless steel material, which has good corrosion resistance, anti blow design, and better use. The sealing materials are fluororubber (FPM), carbonized PTFE+C, PEEK, which have the characteristics of high strength, high temperature and high pressure resistance, good corrosion resistance, and long service life.

8. The ball is made of high-performance stainless steel, and after processing, it is tracked and tested by the Tokyo Precision Roundness Tester RONDCOM30C in Japan, with very precise accuracy.

9. Executive standards: GB/T12237-2007, API6D, ASME B16.34;
