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 over 570 ℃ and a pressure resistance level of PN160~PN420; Both ends are connected by butt welding (BW) and fully welded to the pipeline to eliminate the risk of leakage; The precision conical needle valve core, combined with hard alloy or metal sealing structure, ensures excellent flow regulation accuracy and tight shut-off performance under high temperature and high pressure, and is widely used in harsh working conditions such as power plants, petrochemicals, hydrogen energy, and supercritical fluids.
Adopting a 90 ° right angle flow channel design, it is suitable for pipeline systems with high pressure, high viscosity, or media containing micro particles. The conical needle valve core is matched with a hard alloy sealing surface to achieve precise flow regulation and tight shut-off.
The high-pressure welding needle valve adopts an integral forging structure, and the valve body material is mostly carbon steel, alloy steel or stainless steel.
The forged card sleeve high-pressure needle valve is manufactured using integral forging technology, with a sturdy structure and excellent pressure resistance, suitable for fluid control systems with high pressure and high sealing requirements.
