The high-pressure butt-welding double needle valve is integrally forged from high-quality alloy steel or stainless steel, boasting excellent high-pressure resistance.
○ Port type: MTB butt welding (MTS socket welding, ferrule, UBM loose welding, thread, etc.)
○ Operating temperature: -20℃~520℃
○ Pressure environment: 6000PSI, with a maximum of 10000psi (689bar)
○ Diameter: BW3/4" (1/8"-2", 3mm-50mm)
○ Material: 304, 316, 321, Hastelloy, Monel
○ Integrated 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 5% of the rated working pressure with a water pressure of 1.5 times the rated working pressure
The high-pressure butt-welding double needle valve is integrally forged from high-quality alloy steel or stainless steel, featuring excellent high-pressure resistance, high temperature resistance, and sealing performance. With a dual-valve parallel design and compact structure, it facilitates the simultaneous control of on/off of two media paths. The needle valve core allows for precise flow adjustment. The butt-welding connection method provides high strength and good vibration resistance, making it suitable for high-pressure pipeline systems in petroleum, chemical, natural gas, and other industries, ensuring safe and reliable operation for instrument pressure introduction, sampling, or discharge.
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
The high-pressure double needle valve with ferrules is made of high-strength stainless steel and integrates two independent needle valve cores.
The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments;
