- . shall be
- performed in accordance with preventive .
maintenance schedules as a minimum. However, any major corrective maintenance required should always include . routine maintenance requirements. -
~
L The CPS Motor Operate'd' Valve (MOV)-Program-is.a combination of inspections, routine preventive. maintenance ! and periodic testing which is performed, to. ensure-a operability of the valves. .The MOVs performance is dependent on both its mechanical / electrical condition and its ability to operate and achieve the thrust requirements' .
.necessary to open and/or.close the valve under both normal operating and accident conditions which include degraded voltage, seismic ~ events, harsh environmental conditions and extreme delta P/ flow conditions.
This procedure covers the inspection and preventive maintenance for the valves and their motor operators. CPS . No. 8451.02 covers setup of the valves for proper limit switch / bypass operation, setting of the torque switches for required thrust and diagnostic testing. Also included
.in the program is CPS No.-8451.03 which covers repair and overhaul of motor operations. _
-It'is imperative that while performing this procedure that ,
the individual understand the adverse conditions in which the valves may be required to operate, be observant of any t conditions which may affect its operation and resolve any
!' questions with supervision and plant technical, if
!_ required, i Some items which do not effect the operating parameters of the valve may be reworked,.if necessary, in accordance . with the details of this procedure. Items which effect - the operating parameters of the valve are listed in : limitations section of the procedure and will require an . electrical setup, removat.4 or diagnostic test of the MOV . in accordance with CPS No.- 8451.02. 3 5 3.0 RESPONSIBILITY J The Supervisor - Electrical is responsible for ensuring J-the proper implementation and review of this procedure. 5 Page No. 3 of 23 Rev.

CAUTION .
-Do not use lubricants other than those specified in this procedure. Mixing of greases with different soap bases may cause a chemical reaction reducing,the_ lubricating .
properties of the grease, resulting in damage to the-operator. - 8.4.1.1 Check the grease in both geared' limit switches. Ensure Lthe grease is of proper consistency (thick but soft to the touch), in good condition,. uniform in color, and of , sufficient quantity (a minimum of a coating on the gear train) to provide adequate lubrication. This step is not required for SMC-04 operators. NOTE There are only (2) types of grease found in the limit switch gearboxes; Mobil 28 or Exxon-Beacon 325. Mobile 28
. grease is red in color and shall not be added or. mixed with any other color or type of grease. Beacon 325 ranges in color from light gray to green and shall not be mixed with any other color or type of. grease. .
8.4.1.2 (Record) Record type limit switch gear. box lubricant. . c8.4.1.3 (Initial) Visually inspect torque and limit switch shaft penetrations for indications of seal leakage. Slight oil see? age is not cause for seal replacement. In many cases, tigstening mounting bolts as in 8.3.2.7 will stop the oil seepage. , c8.4.1.4 (Initial) Inspect limit switch compartment tasket (and . torque switch compartment gasket on SMC-04) ror damage. - Clean gasket surfaces as necessary to obtain proper seal.

Ensure worm and worm gear are immersed in grease. Remove a small amount of grease from both the upper and lower sections and ensure that it.is clean and free'of any contaminant (dirt, water or-foreign material). Lubricant should be slightly fluid. If grease level is. low, refill using only the grease listed in Appendix B to a sufficient level to immerse the worm and worm gear. See Figure 4. NOTE A small amount of slightly hardened grease may accumulate ~ in the fill plug hole. 'This does not indicate hardening of grease inside the gear case housing. 8.4.2.2 (Record) Record the type of gear case housing lubricant. Should color not reflect grease type as listed on APPENDIX B,-initiate a procedure change to revise Appendix B - accordingly. , 8.4.2.3 On Limitorque operators using a top mounted hand wheel, pump a small amount of the proper grease listed in Appendix B thru the zerk fitting just below the handwheel. - 8.5 Electrical Checkout .- 8.5.1 (Initial) At the MCC, inspect the cubical for any abnormal conditions. : J G

'(1) - Rockwell Valve (2) . Anchor / Darling Valve
.(3) . Yarway Valve This list of torque valves should be used to tighten the packing gland bolt nuts. This has been compiled based upon information received from -
the valve vendors. The torque valves are defined as follows: Normal Torque: Minimum torque required to ti.ghten the nut such that it does not cause leakage. Maximum Torque: Maximum allowable torque. This valve shall never be exceeded without further engineering evaluation. 3 i The torque values indicated above are for gate and globe valves. Specific torque requirements are not required for butterfly and plug y valves'because these valves close and open on limit (not thrust) and packing gland load will not affect their operability. However, this , table may be used as guidelines when performing maintenance on these ;:.
