    ○ Working pressure: 6000PSIG (413bar)~10000PSIG (689bar)

    ○ Port types: BW (butt welding), SW (socket welding), UBM (loose fitting welding), threaded, etc

    ○ Material: Stainless steel SS316, 304, 321, F91, F92, and other special materials


    Performance
    ○ Integrated body structure
    ○ Dual stem design: The upper stem is threaded hardened, and the lower stem is smooth surface hardened
    ○ Lubrication of the upper valve stem thread can isolate the system medium
    ○ The linear operation of the non rotating lower valve stem replaces the spiral operation, thereby avoiding damage to the valve seat and valve tip components, and reducing the friction between the packing and the lower valve stem
    ○ Optional panel installation and rotation
    ○ Double high lock bolts ensure a durable and stable connection of the handle
    ○ The handle comes in multiple colors to choose from


    Application

    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.
