The high-pressure double needle valve with ferrules is made of high-strength stainless steel and integrates two independent needle valve cores.
○ Port type: OD ferrule (BW butt welding, SW socket welding, UBM loose-fitting welding, thread, etc.)
○ Operating temperature: -20℃~520℃
○ Pressure environment: 6000PSI, with a maximum of 10000psi (820bar)
○ Drive mode: straight handle, handwheel
○ Nominal diameter: 3mm~50mm (1/8~2")
○ Material: 304, 316SS, 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 the test is conducted at a water pressure of 1.5 times the rated working pressure, with a 5% margin
The high-pressure ferrule double needle valve is made of high-strength stainless steel, integrating two independent needle valve cores. It features a compact structure and flexible operation, making it suitable for precise control in high-pressure fluid systems. The ferrule-type connection is convenient to install, reliable in sealing, and effective in preventing leakage, with excellent pressure resistance. It is widely used in instrument pressure guiding, sampling, analysis, and hydraulic systems, enabling fine adjustment and reliable shutoff of two-way media, ensuring safe and stable operation of the system.
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.
