J29H-320 Pressure gauge type globe needle valveDetailed product description：

The J29H-320 pressure gauge type globe needle valve has good sealing performance and is generally used for sealing small flow, high pressure gas or liquid (such as steam, oil) media. The types of valves are generally divided into ordinary globe valves, needle globe valves, angle needle valves, instrument needle valves, bellows needle valves, valve groups, etc. The needle type globe valve has good sealing performance and long service life. Even if the sealing surface is damaged, only vulnerable parts need to be replaced to continue using it. The card sleeve type instrument valve has the advantages of easy installation and disassembly, tight connection, high fire prevention, explosion prevention, and pressure resistance, and good sealing performance. It is an advanced connection method valve in power plants, refineries, chemical plants, and instrument measurement pipelines. Manual globe valves and ball valves can be installed at any position in the pipeline.
