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.
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.
