Product Type: JJM1-1.6 (32) P-type 

 Product Name: Pressure Gauge Valve 

 Needle valve spool is a very sharp cone, as if the same needle into the seat, hence the name. Needle valves than other types of valves can withstand greater pressure, good sealing performance, it is generally used for small flow, high pressure gas or liquid sealing medium. Needle valves and pressure gauges used in conjunction with the most appropriate, and generally made the needle valves are threaded connection (of course, flanged and other forms of connection).
