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 high-pressure gauge needle valve is designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters. It adopts an integral forging structure and has a pressure resistance level of PN100-PN420; Usually used for internal thread (NPT/G) or socket welding connections, with convenient installation and reliable sealing; Built in precision conical needle valve core, which can fine tune the medium flow rate and achieve rapid cut-off, effectively preventing pressure shock from damaging the instrument. It is widely used in harsh working conditions such as petrochemical, power, hydraulic and high-pressure gas systems.
