Step Description Expected Duration
1 In many cases it is less costly to replace the entire valve rather than have it repaired. 15.0 minute
2 Remove the handwheel from the stem. 15.0 minute
3 Mark the body – bonnet flanges with a piece of chalk so they can be matched up later. 5.0 minute
4 Remove body-bonnet nuts and bolts. 15.0 minute
5 Carefully remove the bonnet assembly. Be careful not to nick or scratch the wedge seats. 15.0 minute
6 Thoroughly clean the body and bonnet joint surfaces. 15.0 minute
7 Check the body and bonnet gasket surfaces for any scratches or gouges or other irregularities. 15.0 minute
8 In the even the surfaces are marred, they must be filed or machine flat again. If the damage is considerable, the body or bonnet may have to be replaced. A competent valve shop or machine shop may have to be consulted or contact NIBCO Technical Services or your nearest NIBCO representative for help. 15.0 minute
9 With the surfaces now clean and flat again place the gasket on the body and replace the bonnet. Be careful to use the chalk marks to put everything back together the same way it came apart. Always use a new clean fresh gasket. It does not pay to take a chance using the old gasket over again. 15.0 minute
10 Reinstall the body-bonnet nuts and bolts, and then carefully check to see that the body and bonnet are in the same position as when they were separated. 15.0 minute
11 Pressure test the valve for leakage to see if a good joint has been made. 15.0 minute
Step Description Expected Duration
1 Leakage through the stuffing box packing may be stopped by tightening the packing nuts. Excessive tightening may cause difficult operation of the valve and could cause damage to the stem or packing nut. Do not over tighten. The adjustment should be just tight enough to stop the leak. 15.0 minute
2 If the pack gland follower has run out of travel, isolate and depressurize the valve for repacking or the addition of more packing. 15.0 minute
3 Repacking of valves under pressure is not a recommended practice. Prior to proceeding to change packing, it will be necessary to shut down the piping system, remove pressure and drain, and if necessary, allow cooling and/or decontaminating before working on the valve. 15.0 minute
4 For F-609 and M-609 non-rising stem metal seated gate valves, remove the square operating nut by unscrewing the nut on the top end of the stem, also unscrew the two nuts that hold the indicator-post flange in place; this will allow the indicator-post flange to be lifted or slipped off of the stem. Find the two O-ring seals on the inside of the stem-hole bore of the indicator-post flange hub and replace damaged or worn O-rings. For rising-stem, metal-seated gate valves it is not necessary to remove the handwheel. Remove the packing nuts and bolts, slide the pack gland follower, pack gland up out of the way and keep out of the way with tape or some other convenient temporary method. 15.0 minute
6 For resilient-seated gate valves, follow the above and replace the O-ring or split flat rubber seals. 15.0 minute
