TestingEvery JB series needle valve is factorytested for bubble-tight shutoff at 100 psi(6.8 bar) differential pressure.

Shell testing is performed on a samplingbasis at 3000 psig (206 bar) to arequirement of no detectable leakage.

For more information about ASME classes, material groups, and ratings, see the Swagelok Valve Pressure-Temperature Ratings technical bulletin.For more information about pressure ratings of valves with tube fitting end connections, see the Swagelok Tubing Data or Metric Tubing Data catalog. Pressure ratings

of valves with VCR® or VCO® fitting end connections are based on the ratings of the mating fitting; see the Swagelok VCR Metal Gasket Face Seal Fittings orSwagelok VCO O-ring Face Seal Fittings catalog (VCR and VCR fittings available in N series only).

➀ Ratings limited to:■ 200°F (93°C) max with PCTFE stem tip (NKR).■ 250°F (121°C) max with UHMWPE stem packing.■ 450°F (232°C) max with PTFE stem tip (NTR) or stem packing.■ 600°F (315°C) max with PEEK stem packing and 316 SS, alloy 20, alloy 600, alloy C-276, or titanium; 500°F (260°C) max with PEEK stem packing and alloy 400

(alloy 400 available in N series only).

Pressure-Temperature Ratings➀

Ratings are based on manual valves with optional Grafoil® packing. Other packing materials will affect the ratings.See Stem Packing Materials, page 9.

Severe-Service Union-Bonnet Needle Valves 7

Pneumatic Actuator PerformanceMinimum actuator pressures and maximum system pressuresshown in the graphs below are based on factory adjustment ofpacking and stems lubricated with a silicone-based lubricant.

Packing nut adjustment may affect actuator performance. If the load is too low, the packing may leak. If the load is toohigh, the actuator may stall and the valve will not cycle.

Normally Closed

Stemdrive

nut

Normally Closed ActuatorsAdjustment of the actuator stemdrive nut affects actuator springforce, which in turn affects:

■ the maximum system pressurethat can be shut off by the valve

■ the minimum actuator pressurerequired to open the valve.

Figures 1 and 2 show the minimumactuator pressure required to opena normally closed actuator at sys-tem pressure.

Maximum system pressure for a 3Nvalve with normally closed actuator:

■ NR, NTR, or NKR stem—3000 psig (206 bar).

■ NB stem—4400 psig (303 bar).

Maximum system pressure for a 6Nvalve with normally closed actuator:

■ NR, NTR, or NKR stem—3600 psig (248 bar).

■ NB stem—4600 psig (316 bar).

Normally Open ActuatorsThe amount the stem orifice opens beyond the cracked-open position depends on system pressure, flow characteristics, and valve packing nut adjustment.

Figures 3 and 4 show the minimum actuator pressurerequired to close a normally open actuator at system

pressure.

Minimum system pressurerequired to assist the spring in opening the valve:

■ 3N series with normallyopen actuator—1000 psig(68.9 bar).

■ 6N series with normallyopen actuator—500 psig(34.4 bar).

Options and Accessories

N Series and HN Series

Stem Packing MaterialsPTFE packing is standard.To order an optional stempacking material, add astem packing material designator as a suffix to thevalve ordering number. Seepage 2 for pressure-temperature ratings of valves withoptional stem packing materials.

UHMWPE (ultrahigh-molecular weight polyethylene) is intended for service where fluorocarbons are notacceptable. UHMWPE packing is lubricated with nickelantiseize with hydrocarbon carrier; it does not requirepacking supports.

PEEK (polyetheretherketone) packing material is a 2-piecechevron design including PEEK packing supports andmolybdenum disulfide, fluorinated tungsten disulfide-basedlubricant. PEEK packing is not available in normally openor normally closed pneumatically actuated N series valves.

Grafoil is a high-temperature packing material with fluorinated tungsten disulfide-based lubricant; it does not require packing supports. Grafoil is not available inpneumatically actuated N series valves.

Examples: SS-3HNRF4-P; SS-6NBS8-PK; SS-12NBF8-G.

Stem Packing KitsPTFE, UHMWPE, PEEK, and Grafoil stem packing kitsare available. Kits contain stem packing(s), lubricant, andinstructions.

Stem DesignsN series valve orderingnumbers specify NB ballstem tips. HN series valveordering numbers specifyNR regulating stem tips.To order valves with otherstem designs, replace NBor NR in the ordering num-ber with the desired stemdesign designator.

Examples: SS-3NRF2; SS-3HNKRF2.

Sour Gas ValvesValves with female pipe ends are available for sour gasservice. The body and bonnet are annealed 316 stainlesssteel; the stem is alloy 400. Materials for wetted compo-nents are selected in accordance with NACE SpecificationMR0175 for sulfide stress cracking-resistant materials. Toorder, add -SG to the valve ordering number.

■ 316 SS/ASTM A276 gland for 316 SS,steel, and alloy 400 valves, or brass360 gland for brass valves

■ PTFE/ASTM D1710 backup ring andsilicone-based lubricant for all O-ringsexcept ethylene propylene, whichrequires a polyethylene/ASTM D4020backup ring, and molybdenumdisulfide with hydrocarbon-basedlubricant.

■ O-ring.

Options and Accessories

Stem Packing MaterialsTwo-piece chevron-style PFA packing is standard. For anoptional stem packing, add -P for UHMWPE or -PK for PEEKto the ordering number. See Pressure-Temperature Ratings,page 2, for ratings of valves with optional stem packings. Seethe table at right for lubricants used with optional stem packingmaterials.

Examples: SS-ORS2-PSS-20KF4-PK

Stem Packing KitsPFA, UHMWPE, and PEEK packing kits are available. Kitscontain stem packings, springs, lubricant, and instructions.

Cleaning and PackagingEvery Swagelok metering valve is cleaned and packaged inaccordance with Swagelok Specification SC-10. Cleaning andpackaging in accordance with Special Cleaning andPackaging (SC-11) is standard for metering valves with VCRface seal fitting end connections, and is available as anoption for all others.

TestingThe Swagelok S and M metering valve designs have beenshell tested to a requirement of no detectable leakage with aliquid leak detector.

Every Swagelok L series metering valve is tested for bubble-tight shutoff at 100 psig (6.8 bar) differential pressure.

Every Swagelok 31 series needle valve is factory tested withnitrogen at 1000 psig (69 bar). Seats have a maximumallowable leak rate of 0.1 std cm3/min.
