○ Caliber: 1/4 "~1", 6mm~28mm;

○ 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 high-pressure socket welding needle valve adopts an integral forged valve body, with a compact structure and high strength, suitable for high-pressure, high-temperature or high-purity medium systems; The end is connected by socket welding (SW), which facilitates efficient welding and installation of small-diameter pipelines (usually DN ≤ 50), with reliable sealing and good vibration resistance; The nominal pressure can reach PN100-PN420, and the valve core is designed with a precision conical needle shape, combined with hard alloy or metal sealing pairs, to achieve precise adjustment and tight shut-off of micro flow. It is widely used in harsh working conditions such as instrument pressure, hydraulic systems, petrochemicals, and semiconductors.
