9 9 ellows-sealed Valves Options and ccessories Special Cleaning and Packaging (SC-11) Swagelok series valves with VCR end connections and all K 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 STM G93 Level C. To order special cleaning and packaging for series valves with other end connections, add -SC11 to the valve ordering number. Example: SS-4G-SC11 G, K, and W Vacuum Stem Tip/dapter The vacuum stem tip/adapter helps eliminate gas pockets or trapped volumes. Features include: slotted adapter threads vented adapter cavity copper stem tip on G and W series PCTFE stem tip on K series pressure rating equal to that of the standard valve temperature rating of 200 F (93 C) for K series temperature rating of 400 F (204 C) for G and W series. To order, add an adapter designator to the valve ordering number. Valve G, W K Example: -4G-VD G and K Polyimide Stem Tip provides soft-seat shutoff for temperatures up to 400 F (204 C) or where PCTFE is not compatible with the system fluid is available in manually or pneumatically actuated G and K series valves is rated to the same pressure as the standard valve. To order, add -VP to the valve ordering number. Example: SS-4G-VP Copper Stem Tip provides metal soft-seat shutoff for temperatures up to 400 F (204 C) or where PCTFE is not compatible with the system fluid is available in manually or pneumatically actuated G and K series valves is rated to the same pressure as the standard valve. To order, add -CU to the valve ordering number. Example: SS-4G-CU Vacuum Stem Tip/ dapter Designator -VD -V 4KT Colored Toggle Handles lack handles are standard for toggle-operated 4KT series valves. For other colors, add a handle color designator to the valve ordering number. Example: SS-4KT-L K Indicator Switch Transmits a signal to an electrical device indicating either the open or closed position of a pneumatically actuated valve. Features single-pole, single-throw switch rated at 1/2 for 115 V (ac) resistivity. Includes a 24 in. (61 cm) wire lead with an inline clip. Is available assembled on any normally closed K series valve with a 1 series pneumatic actuator or for field assembly. Factory-ssembled Indicator Switches To order a valve with an indicator switch, add M for a normally open switch or M-2 for a normally closed switch to the valve ordering number. Examples: SS-4K-1CM SS-4K-1CM-2 Indicator Switch Kits To order a kit for an existing valve, use ordering number MS-ISK-K-1CM for a normally open switch or MS-ISK-K-1CM-2 for a normally closed switch. Maintenance Kits Stem tip/adapter kits, bellows kits, and gasket kits are available for G, RG, K, and KT series valves.
