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 (1 & 2) fully counterclockwise to remove

all force on regulating spring (3).

4. Disassemble in general accordance with the item numbers

on exploded view.

CLEANING
1. Clean parts with warm water and soap. Do not submerge

bonnet (1 & 2) in cleaning solution, as lubricant will be
removed.

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

with clean, dry compressed air.

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

ASSEMBLY
1. Lubricate adjusting screw threads inside bonnet (1 & 2)

with a small amount of Lubriplate 110 (or equivalent).

2. Assemble the unit as shown on the exploded view.

WARNING

These products are intended for use in industrial

compressed air systems only. Do not use these products
where pressures and temperatures can exceed those listed
under Technical Data.

If outlet pressure in excess of the regulator pressure

setting could cause downstream equipment to rupture or
malfunction, install a pressure relief device downstream of
the regulator. The relief pressure and flow capacity of the
relief device must satisfy system requirements.

The accuracy of the indication of pressure gauges can

change, both during shipment (despite care in packaging)
and during the service life. If a pressure gauge is to be used
with these products and if inaccurate indications may be
hazardous to personnel or property, the gauge should be
calibrated before initial installation and at regular intervals
during use.

Before using these products with fluids other than air, for

non industrial applications, or for life-support systems
consult Norgren.

PANEL MOUNTING DIMENSIONS
Panel mounting hole diameter: 30 mm (1.19")
Maximum panel thickness: 6 mm (0.25")

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

with inlet air connected to the port marked IN.

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.

3. 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 (1 & 2) counterclockwise to remove all force
on regulating spring (3).

2. Apply inlet pressure, then turn adjustment 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.

NOTE

With non-relieving regulators, make pressure
reductions with some air flow in the system. If
made under no flow (dead-end) conditions, the
regulator will trap the over-pressure in the
downstream line.

4. Push lockring on adjusting knob downward to lock

pressure setting. Pull lockring upward to release.
