Needle globe valves have higher pressure resistance and better sealing performance than other types of valves, so they are generally used in pipeline control systems for gas or liquid media with smaller flow and higher pressure. Needle valves are used in conjunction with pressure gauges, and the switch control valves are placed in front of the pressure gauge transmitter.
Special features of needle globe valves: small flow resistance, simple structure, reliable tightness, easy operation, easy maintenance, wide range of applications, good sealing, and long service life.
