Needle valves can withstand greater pressure than other types of valves, with good sealing performance. It is generally used for small flow, high pressure gas or liquid sealing medium. The needle valve used in conjunction with the pressure gauge is the most appropriate. Needle valves are usually made into threaded connection.
