The NP6 Series Needle ValvesNeedle Valves feature a non-rotating lower stem and packing located below the stem threads.

The packing below the stem threads serves the dual purpose of either protecting the thread lubricant from being removed by the media or preventing the thread lubricant from contaminating the media.

Stem packing options include PTFE, elastomers, and flexible graphite. A non-rotating lower stem helps to extend packing life by removing rotation from the packing area.

NP6 valves are capable of working at system pressures up to 6,000 psig (41.3 MPa) CWP at temperatures as high as 700
