Non stagnant ball valve

Non stagnant ball valve
The following is a comprehensive technical analysis of the hysteresis free ball valve:
Core Structure and Design Features
Fully enclosed valve body design
The structure adopts a valve seat that completely wraps around the sphere, eliminating residual space for the medium, which is particularly suitable for the biopharmaceutical and food industries. The inner surface roughness Ra is ≤ 0.6 μ m, which meets the requirements of GMP certification.
Innovation in Sealing Systems
Spring compensated valve stem sealing design, supporting long-term high-temperature operation at 150 ℃
Adopting PTFE+15% glass fiber reinforced valve seat, the wear resistance life is increased by 3 times
Quick installation connection method
Supports ISO standard clamp connections, reducing disassembly and maintenance time by 50%, and eliminating the need to damage pipeline systems during cleaning

無滯留球閥 工藝處理：

1、機械研磨
無滯溜球閥Use a metal polishing wheel to precisely grind and remove surface metal impurities to form a silky smooth surface.
2、電解拋光
無滯溜球閥By using electric polishing to remove sharp edges and smooth depressions on the metal surface, the surface morphology and structure can be improved, forming a closed chromium oxide film and enhancing the corrosion resistance of the pipeline. Before electric polishing, sanitary ball valves should be mechanically polished (mechanical polishing must be grinding and polishing) to make the product surface smoother and eliminate dead corners.
3、光亮退火
無滯溜球閥The stainless steel material used for the valve body is heated online to 1050 ℃ and then rapidly cooled to below 100 ℃ under hydrogen protection. On the one hand, it eliminates internal stress, and on the other hand, it forms a passivation film on the surface of the pipeline to improve its corrosion resistance.
4、酸洗或鈍化
無滯溜球閥The residual particles on the surface of the pipeline can be removed by edge pickling or passivation. Generate a very thin, dense, and well covered passivation film on the surface of the product, which can firmly adhere to the metal surface and improve corrosion resistance.
