Needle Valves/Bleed Valves - PB59 Series

PN49/PB59 Series Needle Valves/Bleed Valves


The PN49 Series is a fully packed needle valve for high pressure and high temperature applications. Produced in a wide variety of inlet and outlet sizes.

For critical services, the PB59 block and bleed valve features a fully packed and backseated block valve along with a fully packed integral bleed valve.


  • Reduce Costs and Installation Time - Hex block and bleed valves minimize threaded connections while combining multiple valve functions.
  • Fully Backseated Bonnets - Prevent accidental stem removal and blowout. The unique design of our fully backseated bonnets minimizes emissions.
  • Non-Rotating Tip (NRT) Stem - Provides tight, repeatable shutoff without the galling or cross-socring that occurs on ball type stems. Because the NRT conical stem tip stops rotating when it contacts the seat, further torque turns the stem, but not the tip, protecting the tip from damage.
