1�8 General Tool Information

1�8�1 Tools: All tools/hexagons are American Standard inch. Large adjustable wrench,

two (2) large screwdrivers, Allen wrench set, set of open/box end wrenches, rubber

or leather mallet, torque wrench (up to 1600 foot pounds/1269 N-m), breaker bar,
and a drive socket set. For recommended tool and wrench sizes refer to Section 6
Tables 6.3 through 6.10.

1�9 Actuator Storage

For applications where the actuator is not put into immediate service it is recommended
that the actuator be cycled with at least once per month. Indoor storage, if available, is
recommended for all actuators. Care should be taken to plug all open ports on actuator
and controls to keep out foreign particles and moisture. Also, actuators should not be

stored in an atmosphere harmful to resilient seals. For extended storage, contact factory.

1�10 Actuator Installation

1�10�1 Since there are many valve and actuator combinations, it is not practical to include

detailed instructions for each type. Mountings are designed to be as simple as
possible to keep guess work out of installation.

Introduction

Service Instructions

124842E Rev. C

1�10�2 Actuators are shipped from the factory with the travel stops adjusted for

NOTE:

The actual "stopping" should be done by the actuator. If the valve does not have internal
stops, adjust the actuator to the full open position. Using this as a reference point, rotate

the valve closed and adjust to the valve manufacturer's specications for total rotation.

1�10�3 Good instrument practices are also recommended. Clean/dry regulated hydraulic

NOTE:

Scale and debris can damage control valves, solenoids, seals, etc.

approximately ninety-degree rotation. Generally it is necessary to make slight

travel stop adjustments once the actuator is installed on the valve. Refer to the

valve manufacturer's recommendations for specic requirements. When the valve

has internal stops, the actuator should be adjusted at the same points.

pressure is essential for long service life and satisfactory operation. It should be
noted that new pneumatic lines often have scale and other debris in them, and
these lines should be purged of all foreign material.

1�11 Actuator Start-up

1�11�1 Prestart-up checks

1. Inspect to ensure the unit has been mounted onto valve properly. Gear

ange mounting bolts, stem key, setscrew(s) are installed and secured

2. No tubing damaged or accessories dislodged during shipping or
installation

3. Indicated position conrms valve position

4. All switching valves in normal operating position as per schematic/
instructions

1�11�2 Check connections:

1. Pneumatic/hydraulic components connected as per schematic enclosed
or in service manual supplied

2. Pneumatic supply connected to the identied ports

3. Electrical connections terminals are secure

4. Wiring as per enclosed diagram or service manual supplied

1�11�3 When actuator is rst put into service, it should be cycled with regulated

pneumatic pressure. This is necessary because the seals have been stationary,
causing them to take a "set". Therefore, the actuator should be operated through

several cycles, exercising the seals, resulting in a service ready condition.

Introduction

Section 1: Introduction

October 2015

1�11�4 The actuator speed of operation is determined by a number of factors including:

1. Power supply line length

2. Power supply line size

3. Power supply line pressure

4. Control valve and tting orice size

5. Torque requirements of the valve

6. Size of the actuator

7. Setting of speed controls

8. Hydraulic manual override (where available)

1�11�5 Due to the interaction of these variables, it is difcult to specify a "normal"

operating time. Faster operating times may be obtained by using one or more of
the following:

1. Larger supply lines

2. Larger control valve

3. Higher supply pressure*

4. Quick exhaust valves

*Not to exceed maximum operating pressure of actuator or control components

Service Instructions

124842E Rev. C

1�11�6 Slower operating times may be obtained using ow control valves to meter

the exhaust. Excessive exhaust ow metering may cause erratic operation.

1�12 Actuator Operation

1�12�1 Controlled Operation: Controlled operation is accomplished by pressurizing and/or

depressurizing the appropriate cylinder inlet(s) of a double-acting.

Do not exceed pressures indicated on actuator nameplate�

1�12�2 Manual Operation: All pressure must be vented or equalized on both sides of the

pneumatic piston prior to manual operation.

checked, using hydraulic pressure.

3�5�2 Cycle the actuator ve times at 10% of the operating pressure, as listed on the

cylinder name tag under maximum pressure.

NOTE:

If excessive leakage across the piston remains, the actuator must be disassembled and the

cause of leakage must be determined and corrected.

3�5�3 Apply operating pressure as listed in step 3.5.2 to one side of the piston and allow

the actuator to stabilize.

3�5�4 Repeat the above procedure for the opposite side of the piston.
3�5�5 If an actuator was disassembled and repaired, the above leakage test must be

performed again.

3�5�6 Shell test the actuator as follows: Apply 1.5 times the pressure listed on the

cylinder name tag to both sides of the piston simultaneously for a period of two
(2) minutes.

Section 3: Actuator Reassembly

October 2015

NOTE:

If any leakage occurs during step 3.5.6 the actuator must be disassembled and the cause of
leakage must be determined and corrected.

3�5�7 If an actuator was disassembled and repaired, the above testing must be

performed again.

3�5�8 Shell Pressure Test – Optional pressure test could be performed on the actuator by

applying pressure to both sides of the piston simultaneously for a period of two (2)
minutes. If any leakage occurs across a static seal, the unit must be disassembled
and the cause of leakage determined and corrected.

WARNING: PED PRESSURE TESTING

The actuator's main pressure bearing parts will be tested in controlled conditions in
accordance with the requirement of PED by pressuring both sides of the piston to avoid

damage and over torquing of the actuator components. If further future testing in the eld

is necessary, Emerson should be contacted for guidance.

3�5�9 After the actuator is installed on the valve all accessories should be hooked up and

tested for proper operation and replaced if found defective.

7�2 Operational Test

7�2�1 Full Stroke Test

The “full stroke test” (“on-line”) must be performed to satisfy the PFD
probability of failure on demand) value. The full stroke test frequencies will be

dened by the nal installer to achieve the dened SIL level.

7�2�1�1 Procedure

7�2�1�1�1 Stroke the actuator/valve assembly two complete open/close

cycles with complete closing of the valve.

7�2�1�1�2 Verify if the open/close cycles functioned correctly

(e.g., check locally, or automatically via logic solver, the correct
movement of the actuator/valve).

Upon successful completion of the above described full stroke test procedure, the “test

coverage” can be considered 99%.

7�2�2 Partial Stroke Test (when requested)

The “partial stroke test” (“on-line”) can be performed to improve the PFD
and to satisfy PFD

partial stroke value is 15% of the stroke and the recommended test interval is

about every one to three months.

7�2�2�1 Procedure

7�2�2�1�1 Operate the actuator/valve assembly for No° 1 open/close

7�2�2�1�2 Verify if the partial stroke test functioned correctly

(average probability of failure on demand) value. A typical

AVG

cycles 15% of the stroke.

(e.g., check locally, or automatically via logic solver, or via the
PST system the correct movement of the actuator/valve was

15% of the stroke).

Section 8: Removal and Decommissioning

8�1 Removal and Decommissioning

WARNING: FOLLOW PROPER PROCEDURE

Always follow safe work practices, when removing and disassembling G-Series actuator.

The below basic procedure should not supersede or replace any customer's plant safety

or work procedures. If a conict arises between this procedure and the customer's

procedures, the differences should be resolved in writing between an authorized
customer’s representative and an authorized Emerson/Bettis representative.

CAUTION: ISOLATE AND POWER OFF ACTUATOR

Make sure actuator is isolated before removing from valve. Turn off the power medium and

bleed off all pressure rst, including storage tank (if present). Next, bleed off pilot pressure

and disconnect pneumatic pressure supply, pilot tubing and electrical wiring (if equipped).

Before starting the disassembly, a large area should be created around the actuator to
allow any kind of movement.

Separate the parts comprising the actuator according to their nature (e.g., metallic, plastic

materials, uids etc.) and send them to differentiated waste collection sites, as provided for

by the laws and provisions in force.
8�1�1 Drain tanks and remove tubing from actuator. Remove accessories (if equipped)

and control from actuator.

8�1�2 Remove all equipment mounted on top of actuator (limit switches, end of stroke

valve, relevant pneumatic/electric connection, etc.).

8�1�3 Remove mounting bolts and the actuator is ready to be removed from valve.

For complete actuator tear down refer to Section 2 of the manual.
