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.
Used for filling steel cylinders with corrosive gases and industrial pipelines and equipment with the same interface.
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 panel mounted ultra-high pressure needle valve is designed for compact space and centralized control, integrated into the instrument panel or test bench, with a pressure resistance of up to 20000psi (about 138MPa).
