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.
Low temperature and high-pressure needle valves are designed specifically for cryogenic conditions, suitable for temperatures as low as -196 ¡æ (liquid nitrogen) or even lower, with pressure ratings up to 10000psi (approximately 68.9MPa).
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 ¡æ or above
The high-pressure socket welding double needle valve is integrally forged from high-quality stainless steel or alloy steel.
