Technical characteristics:

① 3D modeling is adopted for strength design of the valve body, and with reliable calculations plus professional finite element analysis, whether overall structure, flow paths, and materials of the valve body meet the performance requirements is verified. 

② For valve body raw materials, we signed technical agreements with domestic famous manufacturers to customize materials with better mechanical properties and elongation than those of national standard machines. 

③ With external waterproof design, external water vapor is prevented from entering the valve body to damage the electrical components. 

④ Each seal is made of imported hydrogenated nitrile rubber, which has better and more stable sealing effect for hydrogen medium. 

⑤ Spring material with high strength and high hardness, fatigue resistance and good corrosion resistance are selected, and professional software is used to conduct finite element analysis of the spring in the design stage of the cylinder port valve to ensure spring compression rate, stability and reasonable fatigue design. 

⑥ FEP cable line of domestic famous brand is selected, with rated voltage of 600V, and applicable temperature of -60~+200℃. 

(7) The same types of electrical connectors and circuit protector components as imported brands are selected to improve product stability and ensure electrical over-voltage protection. 

⑧ The valve flap gasket is made of PEEK material with excellent performance from the internationally known brand of high performance plastics.
