Instruction Manual KALREZ System Sliding Stem Valves D102136X012 May 2011 scratched nicked or worn replace the valve stem before installing the KALREZ Packing System Check the condition of the packing bore and clean or hone it out as necessary Refer to the appropriate valve instruction manual to replace the valve stem Figure 1 Belleville Spring Stacking Order 7 SPRINGS PACKING FOLLOWER A6642 For key number locations refer to figure 3 Then proceed as follows 1 The original packing flange studs used for standard packing arrangements should be long enough to accommodate the KALREZ packing parts If you determine that the existing studs and nuts should be replaced however due to their condition replace them with new studs and nuts keys 200 and 212 2 Complete all valve maintenance before installing the KALREZ packing system into the bonnet 3 Be careful NOT to position the KVSP packing system adjacent to any lubrication holes in the bonnet which could compromise its sealing performance Note Ensure that the Belleville springs are stacked properly see figure 1 and packing box parts are assembled in the correct order see figure 3 Packing parts cannot function properly if the Belleville springs or other packing parts are not stacked correctly 4 KVSP packing systems should be installed as a complete set NOT AS INDIVIDUAL PIECES OR COMPONENTS 5 All kits include a single use packet of2. KRYTOX GPL 206 high performance fluorinated grease to maximize service life and ease of assembly KRYTOX lubricants are chemically inert to the chemicals regulated under the U S Clean Air Act non reactive to gaseous and liquid oxygen and chlorine services with chemical compatibility consistent with KALREZ and the KVSP Systems Apply the KRYTOX lubricant liberally to both the I D and O D surfaces of each packing set component key 215 before installing All exposed surfaces of the packing assembly should be fully covered Carefully slide the packing down the stem while being careful not to force the packing and damage it on the stem threads Use fiqure 3 to ensure that the packing parts and spring pack are assembled in the correct order Tightening Procedures A modified tightening procedure is recommended for live loading the KVSP System to ensure the correct loading force is used during the life of the packing and to avoid any overcompression of the packing This procedure also creates open space within the spring set that allows dynamic movement of the packing system to compensate for any volumetric changes that occur during thermal cycling KALREZ System Sliding Stem Valves Instruction Manual May 2011 D102136X012 Figure 2 KVSP System Tightening Procedure UNCOMPRESSED FLAT CONDITION FREE HEIGHT COMPRESSED HEIGHT 90AY012600A B2459 The following tightening procedure will change the final load
