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.
The integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
Ultra high pressure and low-temperature needle valve designed for dual working conditions of deep cold and high pressure
High pressure gauge needle valves are specifically designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters
