1. Use of Adjustment tool is optional.

Table 12. Adjustment Tools

Inspect the primary seating surface as well as the

secondary seating surface and sealing surface. If

nicks or other damage are present, start to disassemble

the Secondary Seat™ assembly by removing the internal

retaining ring (key 25D) with retaining ring pliers. Use

care when removing the internal retaining ring as the

spring (key 25F) is compressed and will exert force on

the Secondary Seat disk (key 25C).

5. Remove the Secondary Seat disk (key 25C), spring

(key 25F) and double sided orice (key 25B). Finally,

remove the orice O-ring (key 25E). Lubricate O-ring with

extreme low temperature bearing grease or similar lubricant

that maintains its lubrication properties at cold temperatures

and replace O-ring. Insert the new double-sided orice

(key 25B), then the spring (key 25F), ensuring that the larger

diameter opening is contacting the shelf of the orice.

6. Replace the Secondary Seat disk (key 25C).

See Figure 18.

a. For Types CS805 and CS825 ensure that the

rubber/Nitrile (NBR) sealing surface is facing the

Secondary Seating surface of the orice.

b. For Types CS806 and CS826, ensure that the hole in

the center of the disk that acts as the spring seat is

facing the spring.

7. Press the disk inside the housing (key 25A) to allow the

internal retaining ring to be reinserted.

Note

If the orice is replaced with a different size,

change the nameplate to state the new size

and maximum inlet pressure (see Table 4).

8. Replace O-ring (key 82). Apply anti-seize lubricant to the

external threads of the new orice/orice assembly and

reassemble into the body. Install and tighten the orice

per Figure 12.

9. Reassemble the regulator in reverse order of the above

steps. O-ring (key 28) on end of stem (key 11) should be

lubricated before replacing the disk assembly. The O-ring

is not a pressure retaining part but keeps the disk holder

from rattling on the stem.

Note

See Figure 12, always tighten bolts in a

cross pattern.

Regulator Reassembly

It is recommended that a good quality pipe thread sealant

be applied to pressure connections and ttings and a good

quality lubricant be applied to all O-rings. Also apply an

anti-seize compound to the adjusting screw threads and

other areas as needed. Reference Figures 12 through 18

to determine the recommended lubricant/sealant/adhesive

for these parts. All lubricants/sealants/adhesives must be

selected such that they meet the temperature requirements.

When reassembling, torque bolts and fasteners per torque

values are indicated on Figures 12 through 18. Some

relaxation from initial torque values may occur. Always

tighten bolts in a cross pattern.

Parts Ordering

The type number, orice size, spring range and date

of manufacture are stamped on the nameplate. Always

provide this information in any correspondence with

your local Sales Ofce regarding replacement parts or

technical assistance.

When ordering replacement parts, reference the key

number and the 11-digit Part Number of each needed part

as found in the following parts list. Separate repair part

kits containing all recommended elastomer spare parts

are available.
