Parameter

○ Port type: Threaded (BW butt welding, SW socket welding, UBM sleeve welding, card sleeve, etc.)

○ Working temperature: -20 ℃~520 ℃

○ Pressure environment: 6000PSI up to 10000psi (689bar) maximum

○ Drive mode: One character handle, handwheel

○ Nominal diameter: 3mm~28mm (1/8~1 ")

○ Valve body material: 304, 316, 316L, 321, Hastelloy, Monel alloy

Performance

○ 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

Application

Stainless steel internal thread high-pressure needle valve adopts 304 or 316/316L stainless steel integral forging valve body, with strong corrosion resistance, suitable for chemical, pharmaceutical, food and high-purity medium systems; Internal thread connection (NPT or G) facilitates quick installation of small-diameter pipelines and provides reliable sealing; The nominal pressure can reach PN100-PN420, and the conical needle valve core is matched with a precision ground sealing surface to achieve precise adjustment and tight shut-off of micro flow. It is widely used in high-pressure conditions such as instrument pressure, sampling, hydraulic and high-pressure gas control.
