WARNING

!

To avoid unpredictable system behavior that can cause personal
injury and property damage:

• Disconnect electrical supply (when necessary) before
installation, servicing, or conversion.

• Disconnect air supply and depressurize all air lines connected
to this product before installation, servicing, or conversion.

• Operate within the manufacturer’s specified pressure,
temperature, and other conditions listed in these instructions.

• Medium must be moisture-free if ambient temperature is below
freezing.

• Service according to procedures listed in these instructions.

• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.

• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the product
tested for proper function and leakage. If audible leakage is
present, or the product does not operate properly, do not put
into use.

• Warnings and specifications on the product should not be
covered by paint, etc. If masking is not possible, contact your
local representative for replacement labels.

! WARNING

Product rupture can cause serious injury.

Do not connect regulator to bottled gas.

Do not exceed maximum primary pressure rating.

Introduction

Follow these instructions when installing, operating, or servicing
the product.

Application Limits

These products are intended for use in general purpose compressed
air systems only.

Operating Pressure Range: PSIG bar

PRIMARY – Maximum 150 10.34

SECONDARY – Spring Pressure

40 PSIG Minimum 2 0.14

Maximum 40 2.76

120 PSIG Minimum 2 0.14

Maximum 120 8.27

Operating Temperature Range:

-18°C † to 65°C (0°F to 150°F)

† Temperatures below 0°C (32°F) require moisture free air.

Installation:

1. Regulator should be installed with reasonable accessibility for
service whenever possible — repair service kits are available.
Keep pipe or tubing lengths to a minimum with inside clean
and free of dirt and chips. Pipe joint compound should be
used sparingly and applied only to the male pipe — never into
the female port. Do not use PTFE tape to seal pipe joints —
pieces have a tendency to break off and lodge inside the unit,
possibly causing malfunction.

2. Install regulator so that air flows from “IN” to “OUT” as marked
on the regulator. Installation must be upstream from devices it
is to service (lubricator, valve, cylinder or tool), and mounted
closely to these devices. Mounting may be in any position.

3. Gauge ports are located on both sides of the regulator body
for your convenience. It is necessary to install a gauge or pipe
plug into each port during installation.

4. Remove plastic plug from vent hole in bonnet.

5. For protection against rust, pipe scale and other foreign matter,
install a filter on the upstream (high pressure) side as closely
to the regulator as possible.

that you analyze all aspects of your application, including consequences
of any failure and review the information concerning the product or
systems in the current product catalog. Due to the variety of operating
conditions and applications for these products or systems, the user,
through its own analysis and testing, is solely responsible for making
the final selection of the products and systems and assuring that all
performance, safety and warning requirements of the application are
met.

High Precision Regulator IS-2R205

Operation

1. Before turning on the air supply, turn the adjusting knob
counterclockwise until compression is released from the control
spring. Then turn on air supply and adjust regulator to desired
secondary pressure by turning adjusting knob clockwise. This
permits pressure to build up slowly, preventing any unexpected
operation of the valve, cylinders, tools, etc., attached to the
line. Adjustment to desired secondar y pressure can be made
only with primary pressure applied to the regulator.

2. To decrease regulator pressure setting, always reset from a
pressure lower than the final setting desired. For example,
lowering the secondary pressure from 5.5 to 4.1 bar (80 to
60 PSIG) is best accomplished by dropping the secondary
pressure to 3.5 kPa (50 PSIG), then adjusting upward to 4.1
bar (60 PSIG).

7. Place the new control diaphragm (H) onto the body (K). Put
diaphragm housing (G) on next followed by the new protector
diaphragm (F) and spring (E). Put balance control assembly
(D) on next then the new gasket (C) followed by bonnet
assembly (A) and reassemble the four screws (B). Tighten
screws 3.2 to 3.6 Nm (28 to 32 in-lbs) in progressive steps
using a crisscross pattern.

8. Install new bleed screw (M). Tighten screw 1.5 to 1.9 Nm (13
to 17 in-lbs) in progressive steps using a crisscross pattern.

9. Admit inlet pressure and turn the adjusting knob (A) to obtain
the desired pressure.

NOTE:A slight flow of air through the bonnet vent hole is necessary

for proper operation of the regulator.

CAUTION

REGULATOR PRESSURE ADJUSTMENT - The working range of
the knob adjustment is designed to permit outlet pressures within
their full range. Pressure adjustment beyond this range is also
possible because the knob is not a limiting device. This is a
common characteristic of most industrial regulators, and limiting
devices may be obtained only by special design.

Service: (Always vent all air pressure

before servicing)

1. Turn the control knob (A) fully counterclockwise. Remove
upstream air supply.

2. Remove four screws (B) holding the bonnet (A) in place.
Remove bonnet assembly, gasket (C), balance control assembly

(D), spring (E), protector diaphragm (F), diaphragm housing
(G), and control diaphragm (H). Discard gasket (C), protector

diaphragm (F), and control diaphragm (H).

3. Remove bleed screw (M) and discard.

4. Remove spring retainer (L) and spring (K).

5. Clean all retained parts with mild soap and water.

6. Install spring (K) and spring retainer (L) into body making sure
that the spring is installed correctly, see Fig. 1. Tighten spring
retainer 2.6 to 3.1 Nm (23 to 27 in-lbs).
