J23W-160P

The product structure form of the J23W-160P high-pressure needle valve is external thread connection, 

so it is also called an external thread needle stop valve. There are many types of high-pressure needle valves,

 with models such as A21W and A24W. Needle valves feature easy installation and disassembly, tight connection,

 fire prevention and explosion prevention, high pressure resistance, and excellent sealing performance. They are 

widely used in industries such as chemical engineering, power, hydraulic machinery, and petroleum and natural gas. 

High-pressure needle valves are more pressure-resistant and have better sealing performance compared to other valves. 

Therefore, they are generally used for sealing gas or liquid media with smaller flow rates and higher pressures. 

Needle valves are most suitable to be used in combination with pressure gauges. Generally, needle valves are

 made in the form of threaded connection and ferrule connection.
