○ 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

The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments; The valve body is made of integral forged stainless steel or alloy steel, with a pressure resistance of PN100-PN420; Built in precision conical needle valve core, achieving precise adjustment and reliable shut-off of micro flow, widely used in pressure gauges, transmitter pressure pipelines, and high-pressure, high-temperature, or high-purity medium systems that require frequent maintenance, while ensuring sealing and improving installation flexibility.
