Severe-Service Union-Bonnet Needle ValvesSpecial Alloy Materials 7 Options N Series and HN Series Stem Packing Materials PTFE packing is standard. Stem Packing To order an optional stem Material packing material, add a stem UHMWPE -P packing material designator to the valve ordering number. See page 2 for pressuretemperature ratings of valves with optional stem packing materials. PEEK Grafoil -PK -G UHMWPE (ultrahigh-molecular weight polyethylene) is intended for service where fluorocarbons are not acceptable. UHMWPE packing is lubricated with nickel antiseize with hydrocarbon carrier; it does not require packing supports. PEEK (polyetheretherketone) packing material is a 2-piece chevron design including PEEK packing supports and molybdenum disulfide, fluorinated tungsten disulfide-based lubricant; stem packing replacement kits also contain nickel antiseize with hydrocarbon carrier. Grafoil is a high-temperature packing material that does not require packing supports. Factory assemblies contain fluorinated tungsten disulfide-based lubricant and nickel antiseize with hydrocarbon carrier; stem packing replacement kits contain only nickel antiseize with hydrocarbon carrier. Examples: 625-3HNRF4-P 625-6NBS8-PK-625 625-12NBF8-G-625 Stem Packing Kits PTFE, UHMWPE, PEEK, and Grafoil stem packing kits are available. Kits contain stem packing(s), lubricant, and instructions. Valve Series Special Cleaning and Packaging (SC-11) To order N series and HN series valves with optional cleaning and packaging to ensure compliance with product cleanliness requirements stated in ASTM G93 Level C, add -SC11 to the valve ordering number. Example: 625-3NBF2-SC11 Seal Material and Kit Ordering Number PTFE UHMWPE Grafoil PEEK 3N, 3HN T-9K-3N PE-9K-3N G-9K-3N PK-9K-3N 6N, 6HN T-9K-6N PE-9K-6N G-9K-6N PK-9K-6N 12N T-9K-12N PE-9K-12N G-9K-12N PK-9K-12N Lubricant Nickel antiseize with hydrocarbon carrier Nickel antiseize with hydrocarbon carrier and fluorinated tungsten disulfide-based; molybdenum disulfide-based coating Oxygen Service Hazards For more information about hazards and risks of oxygenenriched systems, see the Oxygen System Safety technical report, MS-06-13. Sour Gas Service special alloy N series severe-service union-bonnet needle valves are available for sour gas service. Materials are selected in accordance with NACE MR0175/ISO 15156.

A packing adjustment may be required periodically to increase service life and to prevent leakage. Valves that have not been cycled for a period of time may have a higher initial actuation torque. To increase service life, ensure proper valve performance, and prevent leakage, apply only as much torque as is required to achieve positive shutoff. Safe Product Selection When selecting a product, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user.
