  Instrument needle valve overview:

The spool of a needle valve is a very pointed cone, which is named after being inserted into the valve seat like a needle. Needle valve can withstand greater pressure than other types of valves, and has good sealing performance, so it is generally used for sealing of gas or liquid medium with lower flow and higher pressure. ( 当然也有法兰及其他形式的连接 ) Needle valves and pressure gauges are most suitable for use together. Generally, needle valves are made with threaded connections (of course there are flanges and other forms of connection ) .
