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.
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
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
