Hydrogen specific valve

Brand：Pneumatic eccentric butterfly valve 型号：WJ40F

The R hydrogen dedicated valve is a high-performance control device designed for the special physical and chemical properties of hydrogen, such as low density, flammability, explosiveness, and easy leakage.
1、 Core technical characteristics
Ultra low leakage sealing technology
By adopting a molecular level sealing structure (such as the sealing ring and protrusion designed by Chenchen Green Energy patent), the leakage rate can be controlled within ≤ 1 × 10 ⁻⁶ mbar · L/s
Multiple sealing designs (such as Tress' patented hard alloy overlay welding+pad pressure sealing) enhance valve port wear resistance
Material anti hydrogen embrittlement treatment
The main material is selected from 316L stainless steel, nickel based alloys (such as Inconel 625), or specially treated aluminum alloys
Priority should be given to hydrogen compatible fluororubber (FKM) or metal seals as sealing materials
Security protection design
Integrated static elimination device (conductive coating/grounding) to prevent spark risk
Some valves are equipped with safety relief devices (such as safety valves for pressure reducing valves)
