15If possible, backseat the valve to limit entry of foreign material into valve and to aid in valve stem inspection.Remove and clean the packing gland nutsRaise packing gland and, if necessary, tie gland clear of the stuffing box.Clean any chemical build up or deposits on gland and stem. Use care not to score the stem or stuffing box during packing removal.Remove old packing from valve using a packing extractor or, if packed with GTPI, a machinist scribe. Insure all packing is removed.Clean stem and stuffing box of all residue.
16The valve stem and stuffing box wall should be smooth and free of any series of pits, cuts, scratches or nicks in a line that could possibly act as a path of leakage regardless of their depth. If the stem or stuffing box is excessively pitted notify the proper personnel.Stem roughness and/or high spots will destroy the packing. Scale can permit leakage through itself and thus around the packing.Stem diameter tolerances ±.003.Stuffing box diameter tolerancesStuffing box finish RMS.Normality, squareness, and parallelism within .005, not more than .015 on any single surface.The valve stem and stuffing box should be free of excessive wear, scale and corrosion. Do not repack if this criteria is not met.
17On an accessible section of the valve stem, verify the stem finish is RMS. This test is to evaluate the overall machined surface of the stem, it is not an evaluation of random minor pitting. A simple method to make this evaluation is by dragging a fingernail first over a standard finish block and then over the lay or ridges of the stem finish.If the stem does not meet this criteria, do not repack the valve with pure graphite style packings. With proper approval the stem may be removed from the valve and polished to meet this criteria.If the stem cannot be reworked to meet this criteria, repack the valve with Chesterton 1601 or approved equivalent.
20Installation of RingsInsure that the stuffing box is clean and free of debris.Wear protective gloves to insure there is no contamination of packing rings.Lightly coat pitted valve stems (Manual valves) with Chesterton 772 Premium Nickel Anti-Seize Compound.Install carbon sleeves if necessary following requirementsInstall a One-CI cut ring to the bottom of the stuffing box. Seat the ring by using a Chesterton Valve Tamping Tool.Install correct quantity of 5300/5800 die formed rings.Rings are usually supplied with a single skive cut whose joints shall be staggered 180° apart. If rings are supplied with a double cut (two halves) or for the 5800 stagger joints 90° apart.Double cut rings are sometimes required because of valve design or stiffness of rings. Care should be taken not to mix halves.Rings that are single cut must carefully be twisted open and installed around stem rather than spreading them apart.Gently preseat each ring using a Chesterton Valve Tamping Tool.Install a One-CI cut ring on top. Be sure to seat ring properly.The last One-CI cut ring should be flush or below the top of the stuffing box, never above.
