4.Use retaining ring pliers to remove the top plate (6)

and retaining ring (7). Pull cap (8) and o-ring (9) from

body.

5.Unscrew socket head screw (1), then remove button

(2), spring (3), knob (4), tumblers (5), coupling (10),

and o-ring (11).

6. Remove, as an assembled unit, the adjusting screw

(12) with upper and lower piston assemblies (items

13 thru 19). Remove spring (20).

7. Unscrew the adjusting screw (12), then separate

upper and lower piston assemblies (items 13 thru

19). The adjusting screw has left hand threads.

Make sure o-ring (18) remains attached to the lower

piston (17). If not, retrieve it from inside the upper

piston (13).

8. Unscrew bottom plug (21) to gain access to the

parts (22 thru 33) located in the lower portion of the

body.

CLEANING

1.Clean parts with warm water and soap.

2.Rinse and dry parts. Blow out internal passages in

body (34, 35) with clean, dry compressed air.

3.Inspect parts. Replace those found to be damaged.

ASSEMBLY

1. Lubricate o-rings, o-ring sealing surfaces, and the

adjusting screw threads (12) with a small amount of

good quality o-ring grease.

2. Assemble the lower piston (16*, 17, 18,19), the

regulating spring (15), and upper piston (13, 14),

then turn the adjusting screw (12) into the assembly

until the tip of the screw is flush with the bottom of

the lower piston (17). The adjusting screw has left

hand threads. Place spring (20) in position in the

body, then place the upper and lower piston

assembly (items 12 thru 19) in the body.

3. Insert coupling (10) and o-ring (11) into cap (8).

Place tumblers (5), knob (4), spring (3), and button

(2) in position and secure with screw (1). Make

sure button (2) is installed with the large end

(marked A) up. Place o-ring (9) in position on the

cap (8), then place the cap and knob assembly

(items 1 thru 5, and 8 thru 11) in body, making sure

coupling (10) engages the adjusting screw (12).

4. Use retaining ring pliers to install retaining ring (7),

then install and top plate (6).

WARNING

Make sure retaining ring (7) is fully seated in the

groove in the body.

5. Install the lower section parts (items 21 thru 33)

into body (34 or 35).

3 to 4 (0.3 to 0.5). Screw head

must not extend more than

0.050" (1.3 mm) above top of

button (2).

7. Set the R24 for normal operation as described in

paragraph 1-2, page 2 before it is returned to

service.

* Item 16, washer, is used only with 1/4", 3/8", and

1/2" ported R24 regulators manufactured from

September, 1993 to March, 1994. The design of the

piston (17) was changed in early 1994, and washer

(16) was eliminated. The washer support ribs on the

early pistons (Detail A of exploded view) are

recessed approximately 0.188" (5mm) to

accommodate washer (16). The support ribs on

current pistons are recessed approximately 0.063

(2mm). Discard washer (16) when replacing the

early piston with a current piston.

TECHNICAL DATA

Fluid: Compressed air

Maximum inlet pressure: 300 psig (20 bar)

Operating temperature: 0° to +150°F (-20° to +80°C)

Air supply must be dry enough to avoid ice

formation at temperatures below +35°F (+2°C).

Typical flow at 150 psig (10 bar) inlet pressure, 90 psig

(6.3 bar) set pressure, and 15 psig (1 bar) droop

from set:

1/2" ports: 200 scfm (94 dm

/s)

1-1/4" ports: 700 scfm (330 dm

/s)

Maximum bleed rate at 50 psig (3.5 bar) outlet

pressure: 0.031 scfm (0.015 dm

/s). Maximum bleed

rate occurs under dead-end (no flow) conditions.

Port sizes:

PANEL MOUNTING DIMENSIONS

Panel mounting hole diameter: 1.26" (32 mm)

Maximum panel thickness: 0.12" (3 mm)

INSTALLATION

1.Shut off air pressure. Install regulator in air line -

● with air flow in direction of arrow on body,

● upstream of lubricators and cycling valves,

● as close as possible to the device being serviced.

● at any angle.

2.Connect piping to proper ports using pipe thread

sealant on male threads only. Do not allow sealant to

enter interior of regulator.

Install a pressure gauge or plug the gauge ports.

Gauge ports can also be used as additional outlets for

regulated air.

4.Install a Norgren general purpose filter upstream of

the regulator.

ADJUSTMENT

1.Before applying inlet pressure to regulator, turn

adjustment (4) counterclockwise until knob stops.

2.Apply inlet pressure, then turn adjustment (4)

clockwise to increase and counterclockwise to

decrease pressure setting.

3.Always approach the desired pressure from a lower

pressure. When reducing from a higher to a lower

setting, first reduce to some pressure less than that

desired, then bring up to the desired pressure.

4. If desired, a maximum or minimum outlet pressure

adjustment limit may be set. See page 2 for

instructions.

DISASSEMBLY

1.Regulator can be disassembled without removal from

air line.

2.Shut off inlet pressure. Reduce pressure in inlet and

outlet lines to zero.

3.Turn adjustment (4) fully counterclockwise.

WARNING

Prior to performing step 4, make certain air

pressure upstream and downstream of the R24 is

zero psi.
