Emerson 99 Manuál s instrukcemi stáhnout pdf (Strana 11)

Type 99

diaphragm plate (key 10), pusher post assembly

(key 8) and diaphragm rod (key 4) must be mounted

on the ball of the lever (key 9) so that the pusher

post (key 8) orientation is as shown in Figure 9.

12. Install the upper casing (key 56, Figure 9) and

secure it to the lower casing (key 29) with the twelve

cap screws (key 12) torque 580 to 920 in-lbs /

65.5 to 104 N•m and hex nuts (key 13). Put lower

casing (key 29) back on body and install union nut

(key 14).

CAUTION

To avoid part damage due to over

compressing the main spring seat (key 2),

always use main spring seat 1E242724092

with main spring 0W019127022.

13. Thread the main spring seat (key 2) to the bottom

of the diaphragm rod (key 4) threads and then

back out 1 revolution.

14. Install a new spring case gasket (key 57, Figure 9),

the spring case (key 1) and the four cap screws

(key 58) with 340 to 420 in-lbs / 38.4 to 47.5 N•m

of torque, making sure the indicator stem, O-ring

and gaskets (keys 103, 111 and 108, Figure 6) are

installed, if used.

15. Connect the loading tubing, then refer to

the Startup section for putting the regulator

into operation.

Type 61L, 61LD, 61LE (Low) or 61H

(High Pressure) Pilot

This procedure is to be performed if changing the

control spring for one of a different range or if inspecting,

cleaning or replacing any other pilot parts. Key numbers

are referenced in Figure 9 through 15.

1. Remove the closing cap (key 46), if used, and

unscrew the adjusting screw (key 45) to relieve

control spring compression.

2. Disconnect the loading tubing (key 53) and pilot

supply tubing (key 24).

3. Unscrew the eight cap screws (key 47) and remove

the pilot assembly from the lower casing (key 29).

4. Use the projecting prong in the relay valve body

(key 39) as the restraining member and remove

the diaphragm nuts (key 13, Figure 9 and key 51,

Figure 11). Separate the parts and inspect the

diaphragms (keys 30 and 40) and O-ring seal

(key 33). Replace if worn or damaged.

5. Unscrew the bleed orice (key 52, Figure 11)

from the yoke (key 37). Also to be removed with

the bleed orice are the relay disk assembly

(key 48) and bleed valve (key 50). These parts can

be unthreaded for inspection and replacement,

if necessary.

6. When reassembling the pilot, the relay disk holder

assembly (key 48, Figure 11) and both diaphragms

(key 30, Figure 11 and key 40, Figure 12) should

be tightened on the yoke (key 37) after it is placed

in the body.

Note

Before putting the relay spring case over

the diaphragm, make certain the yoke is

square with respect to the prong in the

relay body. (The yoke can bind on the

prong if it is not square.)

7. Use care in reassembly to be sure the edges of

the diaphragms (key 30, Figure 11 and key 40,

Figure 12) slip properly into the recess on the

lower casing (key 29, Figure 9) and relay valve

body (key 39). With the pilot in place, check to

see if it can be rocked. If it does not rock, it is in

place and the diaphragms (key 30, Figure 11 and

key 40, Figure 12) are free of wrinkles. With both

diaphragms rmly in place, install the cap screws

(key 47, Figure 9) using torque 150 in-lbs / 16.9 N•m

of torque. Tighten using a crisscross pattern to

avoid placing a strain on the unit. Set the pilot

control spring (key 43) according to the adjustment

information in the Startup section.

8. Reinstall the closing cap (key 46, if used). If you

have a plastic closing cap, be sure that you have a

vent (key 60) in place of the pipe plug installed in

the low-pressure pilot spring case (key 44).

Type 61HP (Extra High Pressure) Pilot

This procedure is to be performed if changing the

control spring for one of a different range, or if

inspecting, cleaning or replacing any other pilot parts.

Key numbers are referenced in Figure 18 unless

otherwise specied.

1. Unscrew the adjusting screw (key 45) to relieve

control spring compression.

2. Disconnect the loading tubing (key 53, Figures 9

and 18) and pilot supply tubing (key 24, Figure 9).

3. Remove the six cap screws (key 123) which fasten

the spring case (key 44), spring seat (key 68) and

control spring (key 43) to the pilot body (key 39).
