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 high-temperature and high-pressure welded needle valve adopts an integral forged alloy steel or stainless steel valve body, with a temperature resistance of up to 570 ℃ or above
The high-pressure socket welding double needle valve is integrally forged from high-quality stainless steel or alloy steel.
The forged and welded high-pressure needle valve adopts an integral forging structure, with no casting defects in the valve body, high strength, and good impact resistance
