○ Applicable media: LNG, LO2, LN2, LAr, CO2
○ Caliber: 3mm-28mm (1/8 "-1")
○ Port type: ball joint connection and other interface forms
○ Material: 304, 316L, 321, Hastelloy, Monel alloy, etc
○ 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 integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
High pressure gauge needle valves are specifically designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters
