○ Working pressure: 6000PSI, up to 10000psi (689bar) maximum

○ Nominal diameter: M20 * 1.5-UMB14

○ Port form: UMB welded pipe, threaded

○ Product materials: carbon steel, stainless steel, 1Cr18Ni9Ti, SS316, C276 Hastelloy, Monel alloy, TA2 titanium alloy, 904L

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.
