7. Always replace the sealing washer (key 23), with a

new sealing washer and follow recommended torque

values for hex nut, (key 13).

8. a. Reassemble in reverse order. Tighten the screws

(key 9) using 20 in-lbs / 2.2 N•m torque to install

the disc retainer (key 8) properly.

CAUTION

Failure to properly center the disc

retainer to the disc holder may result in

improper function of the valve.

Important

During replacement of the seat disc, use

P/N GE45079X012 provided to center

the disc retainer to the disc holder

(See Figure 5). Line up holes and insert

screws. Keep the alignment tool inserted

until all of the screws are tightened

to specification.
Alternately, the stem assembly (key 2) and

spring seat (key 4) may be used as shown

in Figure 5 to perform this alignment. After

assembly, check to make sure there is no

interference of the spring seat and disc

retainer when the valve is in the excess

flow position.

b. Apply Medium-Strength Threadlocker on the

stem threads before installing the hex nut

(key 13).

Parts Ordering

Important

Use only genuine Fisher™ replacement

parts. Components that are not

supplied by Emerson should not,

under any circumstances, be used in

any Fisher valve, because they will

void your warranty, might adversely

affect the performance of the valve and

could give rise to personal injury and

property damage.

When corresponding about this equipment, always

reference the equipment type number found on

the nameplate.
When ordering replacement parts, reference

the complete 11-character part number for each

needed part.
