Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
○ Port type: Card sleeve (BW butt welding, SW socket welding, UBM sleeve welding, threaded, etc.)
○ PTFE packing: Operating temperature -34 ° C to 120 ° C (-29 ° F to 248 ° F)
○ Graphite packing: Operating temperature -54 ° C to 520 ° C (-65 ° F to 968 ° F)
○ Pressure environment: 6000PSI up to 10000psi (689bar) maximum
○ Drive mode: One character handle, handwheel
○ Nominal diameter: 3mm~28mm (1/8~1 ")
○ Valve body material: Hastelloy (304, 316, 321, carbon steel, alloy material, etc.)
○ Dual stem design: The upper stem is threaded hardened, the lower stem is smooth surface hardened, and the lubricating grease on the threads of the upper stem is isolated from the system medium
○ The linear operation of the non rotating lower valve stem replaces the spiral operation, thereby avoiding damage to the valve seat and valve tip components
○ Reduce the friction between the packing and the lower valve stem
○ Valve accessories can be selected according to different pressures, temperatures, and media to ensure that the valve will not leak under specific working conditions
○ At the corresponding temperature, the seal will not experience loose sealing
○ It can also be achieved by replacing the valve core to cut off and adjust the flow
○ The entire valve stem can also be customized according to user needs
○ Optional sealing materials: PTFE, PPL, graphite
○ Optional valve panel fixation
○ The handle has multiple colors or handwheels to choose from
○ Each valve undergoes a sealing test before leaving the factory, and is subjected to a sealing test at 5% of the rated working pressure and 1.5 times the water pressure
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3, which have excellent resistance to strong acids, strong bases, and chloride ion corrosion. They are suitable for extremely corrosive media such as wet chlorine gas, hydrochloric acid, sulfuric acid, etc; The overall forging structure can withstand pressure up to PN100 or above, coupled with precision needle valve cores and metal seals, achieving precise flow regulation and zero leakage shut-off under high pressure. It is widely used in harsh working conditions such as chemical, petrochemical, pharmaceutical, and marine engineering.
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.
