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.
Internal thread high-pressure low-temperature needle valve is a precision valve designed specifically for extreme working conditions
The high-temperature and high-pressure socket welding needle valve is made of integral forged heat-resistant alloy steel or stainless steel
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
