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 ultra-high pressure needle valve is designed specifically for ultra-high pressure working conditions, with a compact structure and strong blast resistance.
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.
