High pressure gas cylinder valves are used for filling steel cylinders with corrosive gases and industrial pipelines and equipment with the same interface. The working pressure usually ranges from 15MPa to 68.9MPa (some can reach 50MPa). Made of brass, stainless steel or alloy steel materials, it has excellent sealing, pressure resistance and impact resistance. The interface meets international standards (such as CGA, DIN, BS) and is widely used in industrial gas, medical, fire protection and special gas storage and transportation systems to ensure safe and reliable gas supply.
Ball head welded needle valve bodies are mostly made of integral forged stainless steel or alloy steel, with a pressure resistance of PN420 or above
Specially designed for high-voltage testing and control systems, with a pressure rating of 20000-60000 psi (138-414MPa).
Stainless steel internal thread high-pressure needle valve adopts 304 or 316, 316L stainless steel integral forging valve body, with strong corrosion resistance
