Instrument needle valve It is an important part of the instrument measurement pipeline system, mainly used to open or cut off pipeline access. The valve core is a thin cone, inserted into the valve seat like a needle, so it is named. This valve is characterized by accurate flow adjustment, and its shape can withstand greater pressure than other types of valves, with good sealing performance. Therefore, it is generally used for sealing gas or liquid media with smaller flow and higher pressure.

The main types of instrument needle valves include globe valves and ball valves. The ferrule type instrument valves have the advantages of easy installation and disassembly, tight connection, fire protection, high explosion-proof and pressure resistance, and good sealing performance. They are advanced connection valves in power stations, oil refining, chemical plants, and instrument measurement pipelines.

In general, the instrument needle valve plays an important role in the instrument measurement pipeline system. Its excellent performance and accurate control ability make it widely used in various fields.
