○ Integrated body forging, valve stem transmission thread copper alloy structure
○ Made of all stainless steel or special low-temperature alloy material
○ The valve seat and valve core are filled and welded with STL nickel based alloy, and the valve core has a relatively inverted seal
○ Top mounted design of valve stem packing
○ All valves undergo pressure testing
○ The valve body has a compact structure and reliable sealing, with excellent resistance to cold brittleness and micro leakage control capability
○ All valves have been cleaned and meet the requirements of G-4.1 of the American Compressed Gas Association, and can be used for liquid oxygen equipment
○ Used for low-temperature and high-pressure fluid systems such as LNG, air separation, hydrogen energy, and superconductivity
The ultra-high pressure needle valve is designed specifically for ultra-high pressure working conditions, with a compact structure and strong blast resistance.
Adopting a 90 ° right angle flow channel design, it is suitable for pipeline systems with high pressure, high viscosity, or media containing micro particles. The conical needle valve core is matched with a hard alloy sealing surface to achieve precise flow regulation and tight shut-off.
The high-temperature and high-pressure card sleeve needle valve is made of integral forged heat-resistant alloy steel or stainless steel
