BN Series Bellows-Sealed Valves 7 Options and Accessories Polyimide Stem Tips A PCTFE stem tip is standard. Polyimide stem tips are available in BN4 series valves, for temperatures up to 400 F (204 C) or where PCTFE is not compatible with the system fluid. To order, insert V in the valve ordering number. Example: SS-BNVS4-C Polyimide Stem Tip (Manually operated valve stem tip shown) Replacement polyimide stem tips are available for manually operated valves. Replacement stem tips for pneumatically actuated valves are part of the bellows/stem/stem tip subassembly. See the Swagelok Bellows Valve Maintenance Kits catalog, MS-02-66. Maintenance Kits Stem tip/adapter kits are available for manual BN series valves; bellows/stem/stem tip/adapter kits are available for manual and pneumatic BN series valves. See the Swagelok Bellows-Sealed Valve Maintenance Kits catalog, MS-02-66. Oxygen Service Hazards For more information about hazards and risks of oxygenenriched systems, see the Swagelok Oxygen System Safety technical report, MS-06-13. Toggle Handles Ordering numbers specify rotary handle valves. To order a toggle-operated valve, insert T in the valve ordering number. Example: SS-BNTS4 Black handles are standard Handle Color Designator for toggle-operated BN series Blue -B valves. To order a colored toggle handle, add a handle Green -GR color designator to the valve ordering number. Example: SS-BNTS4-B Orange Red White -OG -RD -WH Yellow -YW Ultrahigh-Purity Process Specification (SC-01) Swagelok BN series valves are processed in accordance with Swagelok Special Cleaning and Packaging (SC-11), MS 06 63, to ensure compliance with product cleanliness requirements stated in ASTM G93 evel C. To order optional cleaning and packaging in accordance with Ultrahigh-Purity Process Specification (SC-01), MS-06-61, for valves with VCR or weld end connections, add -P to the valve ordering number. Examples: SS-BNVCR4-P-C 6V-BNBW4-P Exception: Use ordering number SS-BNFR4-P to obtain SC 01 processing and surface finish for SS BNV51.
