The forged butt welded high-pressure needle valve adopts an integral forging structure, with no casting defects in the valve body, high strength, and good impact resistance. It is suitable for high-pressure, high-temperature, or hazardous medium working conditions, and has butt welded connections (BW) at both ends. Fully welded installation with pipelines to ensure zero leakage, widely used in petrochemical, hydrogen energy, LNG, and high-pressure testing systems; The nominal pressure can reach PN100-PN420, and the valve core is designed with a precision conical needle shape, equipped with a hard alloy sealing surface, to achieve precise adjustment of micro flow and reliable and tight shut-off.
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 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.
