The ultra-high pressure needle valve is designed specifically for ultra-high pressure working conditions, with a compact structure and strong blast resistance.
○ PTFE: Operating temperature -65 ℉ -450 ℉ (-53 ℃ -232 ℃)
○ Graphite: Operating temperature -65 ℉ -1200 ℉ (-54 ℃ -648 ℃)
○ Nominal diameter: SW1/2 "(1/4"~1 ", 6mm~28mm);
○ Port form: SW socket welding (OD sleeve, BW butt welding, UBM sleeve welding, thread, etc.)
○ Valve body material: 316 stainless steel, alloy 400, 20, C-276, and titanium
○ Working pressure: 6000PSIG (413bar)~10000PSIG (689bar)
○ The harsh working conditions combined with the valve cap needle valve can be applied to various harsh working conditions such as high temperature, high pressure, and high erosion.
○ The design of the packing bolt allows for packing adjustment in the open position;
○ The threads of the valve stem and valve stem nut are rolled, greatly improving the thread cycle life;
○ Lubrication of the valve stem thread can isolate the system medium, and the valve seat plays a sealing role after the fully open position is safe;
○ Non rotating spherical valve tip with replaceable adjustable and V-shaped valve heads.
○ Valves can be installed on panels;
The double high lock bolts ensure a durable and stable connection of the handle;
○ The handle comes in multiple colors to choose from;
○ Each valve undergoes a sealing test before leaving the factory, and a sealing test is conducted at 1.5 times the rated working pressure with a water pressure of 5%.
The ultra-high pressure needle valve is specially designed for ultra-high pressure working conditions, with a nominal pressure of PN500~PN1000 (about 50~100 MPa). It adopts an integral forged high-strength alloy steel or stainless steel valve body, with a compact structure and strong blast resistance; The precision ground conical needle valve core and metal to metal sealing pair ensure excellent adjustment accuracy and zero leakage shut-off performance even under extreme pressure, and are widely used in cutting-edge fields such as supercritical fluids, hydrogen energy storage and transportation, high-pressure testing benches, and military research.
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;
