3. CAUTION Damage to the valve disc can occur if the disc is not closed when the valve is being removed from the pipeline If necessary stroke the actuator to place the disc in the closed position while removing the valve from the pipeline 3 Loosen the flange bolting that holds the valve Make sure the valve cannot slip or twist while loosening and removing the bolting 4 Before removing the valve from the pipeline make sure the valve disc is closed Removing the valve with the disc open could cause damage to the disc piping or pipe flanges 5 After removing the valve from the pipeline move the valve to an appropriate work area Always support the valve properly 6 When valve maintenance is complete refer to the Installation procedures in this manual Seal Maintenance Note For larger valves it is possible to replace the seal key 5 while the actuator is mounted to the valve and can be accomplished by cycling the valve to 90 degrees open Key numbers in this procedure are shown in figure 9 unless otherwise indicated 1 After removing the valve from the pipeline remove the manual or power actuator Manually rotate the upper shaft key 3 counterclockwise until the disc has moved a full 180 degrees away from the closed position PA WARNING Avoid personal injury or property damage caused by the impact of a falling or tipping of a large valve Support large valves during maintenance 2 Lay the valve f

6. CAUTION For non ENVIRO SEAL packing Tighten the packing follower nuts only enough to prevent shaft leakage Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem Usually packing leakage can be eliminated by merely tightening the hex nuts key 15 located above the packing follower key 11 while the valve is in the pipeline However if leakage continues the packing must be replaced For PTFE ENVIRO SEAL packing systems refer to the separate instruction manual ENVIRO SEAL Packing System for Rotary Valves Form 5305 see figure 10 CAUTION Never use a wrench or pliers on the splined upper shaft key 3 Instruction Manual Form 5288 November 2007 8532 Valve PACKING FOLLOWER STUD amp HEX NUT ANTI BLOWOUT FOLLOWER HEX JAM NUT VALVE BODY EXTERNAL DETAILS PACKING FOLLOWER STUD AND HEX NUT SPLINED SHAFT PACKING ANTI FOLLOWER BLOWOUT GLAND HEX JAM ANTI NUT BLOWOUT WIRE ANTI BLOWOUT ANTI BLOWOUT FOLLOWER VALVE BODY ANTI BLOWOUT CIRCUMFERENTIAL GLAND SHOULDER TYPICAL PACKING C0758 1 IL CUTAWAY INTERNAL DETAILS FOLLOWER v a id CUTAWAY ENVIRO SEAL PACKING ASSEMBLY Figure 7 Anti Blowout Design Details damaged shaft could cut the packing and allow leakage 1 Before loosening any parts on the valve release the pressure from the pipeline Then remove the h

V ring packing Standard graphite packing is composed of all conductive graphite ribbon packing Alternate shaft to valve body bonding is available for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve see the following step For oxygen service applications provide alternate shaft to valve body bonding according to the following step 8532 Valve Instruction Manual Form 5288 November 2007 4 Attach the bonding strap assembly key 131 figure 6 to the shaft with the clamp key 130 figure 6 5 Connect the other end of the bonding strap assembly to the valve flange cap screws 6 For more information refer to the Packing Maintenance section below Maintenance Valve parts are subject to normal wear and must be inspected and replaced as necessary The frequency of inspection and replacement depends upon the severity of service conditions Key numbers in this procedure are shown in figure 9 unless otherwise indicated ZA WARNING Avoid personal injury from sudden release of process pressure Before performing any maintenance operations Always wear protective gloves clothing and eyewear when performing any maintenance operations to avoid personal injury Disconnect any operating lines providing air pressure electric power or a control signal to the actuator Be sure the actuator cannot suddenly open or close the valve Use bypass valves o
8. during maintenance 1 Properly secure the valve on a suitable worktable so it cannot slip twist or fall during maintenance Be prepared to support the valve disc Note Replacement disc and shafts are provided as a matched set and both should be replaced at the same time 2 Inspect all parts removed from the valve for wear or damage Replace any worn or damaged parts Clean the valve body and all parts to be installed with an appropriate solvent or degreaser Note When installing the bearings apply lubricant to the outside diameter of the bearing for ease of installation CAUTION Premature valve failure and loss of process control may result if bearings are improperly installed or are damaged during installation 3 When installing the lower bearings key 4 insert one or more bearings into the lower shaft bearing bore so it is flush with the body bore The number of bearings required changes with valve size and construction Two bearings are required in the upper shaft and two bearings in the lower shaft If using an NPS 14 CL150 valve with metal bearings four bearings in the upper and four in the lower shaft will be required 4 Hold the lower shaft thrust bearing key 24 in the valve body bore against the counterbore of the lower shaft bearing bore Push the lower shaft into the bearing bore just enough to hold the thrust bearing 5 When installing the upper bearing key 7 insert one or more bearings in
9. the thrust bearings placed on the ends of the shafts 10 With the disc key 2 properly positioned in the valve body key 1 push the upper shaft and lower shaft the rest of the way through the thrust bearings and into the shaft bores in the valve disc 11 Align the holes in the shafts with the holes in the disc CAUTION To avoid damage to the tangential pins disc pins valve disc or shaft s resulting from the application of excessive force use appropriate care when driving the pins into the disc hub and shaft s Use the right tool Do not use excessive force 12 Install the appropriate tangential pins and disc pins Use 2 tangential pins that will go through the upper shaft and 1 disc pin that will go through the lower shaft 13 Refer to the Anti Blowout Design Packing Valve Shaft Disc and Bearing Maintenance procedures in this manual to re install the packing and anti blowout design Gasket Retainer Valves with a two piece shaft use a gasket retainer and gasket keys 20 and 21 to cover the lower shaft opening in the valve body The gasket is held in place by the gasket retainer and four hex head bolts and lockwashers keys 23 and 22 When re assembling the valve use a new gasket Be sure to center the gasket over the lower shaft bore before retightening bolts Tighten down bolts evenly in a crossover or star pattern Refer to table 6 for proper torque values 8532 Valve Instruction Manual Form
