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, with a pressure resistance level of PN100-PN420; Both ends are connected by butt welding (BW), fully welded to the pipeline for installation, ensuring no leakage risk under high temperature, high pressure or hazardous medium conditions; The precision conical needle valve core, combined with hard alloy or metal sealing pairs, achieves precise adjustment and reliable tight shut-off of small flow rates, and is widely used in harsh industrial fields such as petrochemicals, electricity, hydrogen energy, LNG, and high-pressure testing systems.
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.
The high-pressure socket welding needle valve adopts an integral forged valve body, with a compact structure and high strength
The pressure resistance can reach 60000psi (413MPa), and it adopts an integral valve body and conical sealing structure, suitable for precision flow control of high-purity, corrosive or hazardous media.
