The ball joint welded needle valve body is mostly made of integral forged stainless steel (such as 316/316L) or alloy steel, with a pressure resistance of PN420 or above; Equipped with a precision conical needle valve core, it can achieve precise adjustment and tight shut-off of small flow rates, and is widely used in high-end industrial fields such as hydraulic, petrochemical, hydrogen energy, semiconductor, and high-pressure testing equipment.
Ultra high pressure and low-temperature needle valve designed for dual working conditions of deep cold and high pressure
Welding high-pressure needle valves for power plants are designed specifically for thermal power generation, nuclear power, and supercritical units
The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments;
