Parameter

○ Port type: SW socket welding (BW butt welding, ferrule, UBM loop welding, thread, etc.)

○ Operating temperature: -20℃~520℃

○ Pressure environment: 6000PSI, with a maximum of 10000psi (689bar)

○ Diameter: SW3/4" (1/8"-2", 3mm-50mm)

○ Material: 304, 316, 321, Hastelloy, Monel

Performance

○ One-piece forged design

○ Dual valve stem design: upper valve stem with threaded hardening and lower valve stem with surface hardening

○ Isolate the lower valve stem thread lubricant from the system medium

○ Linear, rather than non-rotating, helical movement of the lower valve stem prevents wear and damage to the valve seat and tip, reducing the total friction area between the packing and the lower valve stem

○ Safety back seat seal in fully opened position

○ Each valve undergoes a sealing test before leaving the factory, and is tested at a water pressure of 1.5 times the rated working pressure, with a 5% margin

Application

The high-pressure socket welding double needle valve is integrally forged from high-quality stainless steel or alloy steel, featuring excellent resistance to high pressure, high temperature, and corrosion. The double-valve parallel structure is compact, with each path equipped with a precision needle valve core, enabling independent fine adjustment and reliable shutoff of the two media paths. The socket welding connection method provides firm sealing and strong vibration resistance, making it suitable for high-pressure instrument pipeline systems in the petroleum, chemical, and power industries, ensuring safe, stable, and leak-free operation.
