HN29 Series — Needle Valve
� A new addition to compliment our Series HN39 and HN49valves, is the Series HN29. This new needle valve is tar-geted for the gas sampling, OEM, and reseller market.
All stainless steel valves are rated to 3000 psig @100°F with soft seats, Teflon packing and 1" diameterround knurled handles. Valves are available in 1/4"sizes.
All carbon steel valves are rated to 6000 psig @ 100°Fwith hard seats and 3000 psig @ 100°F with soft seats(Delrin), Teflon packing and either "T" handles or 1"diameter round knurled handles.
� The HN39 Instrument Valves are compact and economicalhigh-pressure instrument valves.
Product Availability
All valves are available with integral hard seats, 316 stain-less steel body and trim and Teflon®//Grafoil packing. Valvesare furnished with a panel mount nut.
Panel manufacturers can use the standard panel nutto secure valves to instrument panel.
Stem tip is non-rotating, standard.
Ratings (Metal Seated)
Stainless Steel: 6000 PSIG @ 100°F (414 bar @ 38°C)• 450°F (232,2°C) limit for Teflon-packed valves• 1000°F (537,8°C) limit for Grafoil-packed valves
� The HN49 is a heavy duty needle valve that features anindustrial strength stem and bonnet, and enhanced pack-ing arrangement, all designed to handle the tough condi-tions of high pressure and high temperature services.
With a multitude of configurations available, you’ll find amodel to meet your varying needs. The HN49 is producedin 1/4", 3/8", 1/2", 3/4", and 1" sizes, and can be providedwith male or female threaded connections, male or femalesocket weld ends, or tube nut connections. For corrosiveor other volatile applications, the HN49 can be specified ina variety of materials including Monel®, Alloy 20, Tita-nium, and Hastelloy®.
Refer to Page 11 for information concerning the 10,000#bonnet.
� NRT Non-Rotating Tip Stem
Provides tight repeatable shutoff without the gall-ing or cross-scoring that occurs on ball typestems. Because the NRT conical stem tip stopsrotating when it contacts the seat, further torqueturns the stem, but not the tip, protecting the stemtip from damage.
Repeated closures improve the mating betweenthe seat and the stem tip, unlike wear that willoccur over time with a ball stem tip.

Stainless Steel: 6980 PSIG @ 100°F( 481,2 bar @ 37,8°C); 3525 PSIG @ 1000°F(243,0 bar @ 537,8°C)Carbon Steel: 6580 PSIG @ 100°F(453,7 bar @ 37,8°C); 4300 PSIG @ 650°F(301,3 bar @ 37,8°C)
• 450°F (232,2°C) limit for Teflon
Features
� Backseated Bonnets with Packing Below theStem Threads
To eliminate potential thread contamination by theprocess media, the packing is located below thestem threads. Backseating minimizes fugitiveemissions with a metal-to-metal backseat thatalso prevents accidental removal or stem blow-out in operation.
� Wide selection of Packing Materials
Choose fully packed (TFE-Chevron or high tem-perature graphite) bonnets, or o-rings seals.
The 10,000# bonnet assembly was added to the Hex prod-uct line to meet the very high-pressure requirements in oiland gas production, specifically on offshore drilling plat-forms.
The 10,000# bonnet assembly is used in our HN49 SeriesInstrument Valves and be rated at: 10,000 psig @ 100° F(689,5 bar @ 37,8° C); 6900 psig @ 450° F (475,7 bar @232,2° C).
Note that the bonnet is only available with Teflon packing.
The 10,000# bonnet is not interchangeable with other Hex bonnets, as the sealing between the bonnetand body are different.
