The high-temperature and high-pressure socket welding needle valve is made of integral forged heat-resistant alloy steel or stainless steel, suitable for harsh working conditions with temperatures up to 570 ℃ and pressures up to PN420; The end is connected by socket welding (SW), which facilitates efficient welding and installation of small-diameter pipelines, with reliable sealing and strong resistance to thermal cycling; The precision conical needle valve core and metal hard sealing structure ensure precise adjustment of micro flow and zero leakage shut-off, and are widely used in key occasions such as power plant instrument pipelines, petrochemical high-temperature reaction systems, and high-pressure steam sampling.
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.
Used for filling steel cylinders with corrosive gases and industrial pipelines and equipment with the same interface.
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.
