Stainless steel internal thread high-pressure needle valve adopts 304 or 316/316L stainless steel integral forging valve body, with strong corrosion resistance, suitable for chemical, pharmaceutical, food and high-purity medium systems; Internal thread connection (NPT or G) facilitates quick installation of small-diameter pipelines and provides reliable sealing; The nominal pressure can reach PN100-PN420, and the conical needle valve core is matched with a precision ground sealing surface to achieve precise adjustment and tight shut-off of micro flow. It is widely used in high-pressure conditions such as instrument pressure, sampling, hydraulic and high-pressure gas control.
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
The high-pressure double needle valve with ferrules is made of high-strength stainless steel and integrates two independent needle valve cores.
The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments;
