3. Unscrew the bonnet (key 3) by turning in a counterclockwise direction from the valve body (key 1). Lift the bonnet

up and off the plug and stem assembly (key 4).

4. Unscrew the lower seat ring retainer (key 5) from the valve body (key 1) and remove the plug and stem assembly

(key 4) (see figure 2). Wipe the parts with a clean soft cloth and examine for signs of wear.

Lapping the Valve Seat

If valve seat leakage becomes excessive, it may be necessary to lap the valve seat.

Lapping is the process of mating the valve plug to the seat ring, with an abrasive to produce a close fit. When valve seat

leakage becomes excessive, lapping becomes necessary. The plug and seat ring seating surfaces should be free of

large scratches or dents and the contact surface of the seats should be as narrow as possible.

1. Use a good quality lapping compound with a mixture that contains 280 to 600 grit. Apply at several spots around

the plug seating surface.

2. Replace the plug and stem assembly (key 4) through the bottom of the valve body (key 1) and screw in the lower

seat ring retainer (key 5).

3. Place the bonnet (key 3) loosely into the valve body to serve as a guide during the lapping operation.
4. Rotate the plug and stem assembly (key 4), applying light pressure to the plug/seat mating surface.
5. Lap as little as possible. Excessive lapping will shoulder the seat ring, and will not improve the seating. Repeat for

the second seating surface.

6. Clean the valve seats and plug thoroughly when the lapping is complete.

Replacing Packing

Refer to figure 2 and the standard and optional packing constructions (figures 3, 4, and 5) to determine the packing

that has been preinstalled in your valve.

1. Mount the valve in a vise.
2. Remove actuator, stem locknuts (key 27), travel indicator (key 58), packing follower (key 7), and yoke drive nut (key

8) per actuator instructions D103352X012.

3. Unscrew the bonnet (key 3) by turning in a counterclockwise direction from the valve body (key 1). Lift the bonnet

up and off the plug and stem assembly (key 4). Push the old packing out from the underside of the bonnet (key 3).

4. Standard Spring Loaded PTFE V-Ring Packing (figures 2 and 3): Carefully insert each piece in exact order shown in

figure 3. Turn the packing follower (key 7) until it shoulders on the bonnet (key 3). This will compress the packing

spring (key 9) to enable constant stem sealing throughout packing life.

5. Molded Graphite Ribbon Packing (figure 4): Carefully insert each piece in exact order shown in figure 4. Hand

tighten the packing follower (key 7). Use a wrench to increase tightness by turning the nut an additional 60

degrees.

6. ENVIRO-SEAL Packing (figure 5): Carefully insert each piece in exact order as shown in figure 5. Tighten the packing

follower (key 7) until the Belleville springs are compressed. This will be signaled by a significant increase in

resistance. Back off the follower 1/8 to 1/4 turn. A gap of approximately 1/16 inch between the packing follower

and the bonnet will ensure packing is seated properly.

CAUTION

Overtightening the packing may prevent stem movement and valve operation and result in equipment damage or loss of

control of the process.
