HH Series High Pressure Needle Valve

Brand: Hex Valve
Does not ship to OH, United States
The HH Series is a heavy duty, high pressure needle valve that features an industrial strength stem and bonnet and enhanced packing arrangement all designed to handle the tough conditions of high pressure service. 

With a multitude of configurations available, you will find a model to meet your varying needs. 

The HH Series is produced in 1/8", 1/4", 3/8", 1/2" NPT ends and 1/4", 3/8" and 9/16" cone and threaded ends. 

For corrosive or other volatile applications, the HH Series can be specified in a variety of materials including Titanium, Hastelloy® and Inconel®.
Features
  • Packing Materials: TFE or high pressure graphite
  • Backseated bonnets with packing below the stem threads: To eliminate potential thread contamination by the process media, the packing is located below the stem threads
  • Non-Rotating Tip (NRT) stem: Provides tight, repeatable shutoff without galling or cross-scoring that occurs on ball type stems
