ST00MC14_Needle Valve_High Pressure Valve_Neptune Valve丨Neptune Industrial Group Inc

Parameter

○ 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

Performance

○ 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

Application

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.
