1�1 General Service Information
1�1�1 This service procedure is offered as a guide to enable general maintenance to
be performed on Bettis G01X0X-M11, G2X0X-M11, G3X0X-M11, G4X0X-M11,
G5X0X-M11, G7X0X M11, G8X0X-M11, and G10X0X-M11 Double-Acting Series
Hydraulic Actuators with –H override module. NOTE: Actuator models may not
have a M11 override but may have a –H Hydraulic Override Module without
a –M11 Override System.
1�1�2 Normal recommended service interval for this actuator series is ve years.
NOTE:
Storage time is counted as part of the service interval.
1�1�3 This procedure is applicable with the understanding that all electrical power and
hydraulic pressure have been removed from the actuator.
1�1�4 Remove all piping and mounted accessories that will interfere with the module(s)
that are to be worked on.
1�1�5 This procedure should only be implemented by a technically competent technician
who should take care to observe good workmanship practices.
1�1�6 Numbers in parentheses ( ) indicate the bubble number (reference number) used
on the Bettis assembly drawing and actuator parts list.
1�1�7 This procedure is written using the stop screw side of the housing (1-10) as a
reference and this side will be considered the front side of the actuator. The
housing cover (1-20) will be the top of the actuator.
1�1�8 Actuator module weights are listed in Section 6 Table 6.2.
1�1�9 When removing seals from seal grooves, use a commercial seal removing tool or a
small screwdriver with sharp corners rounded off.
1�1�10 Use a non-hardening thread sealant on all pipe threads.
CAUTION: FOLLOW MANUFACTURER'S INSTRUCTIONS
Apply the thread sealant per the manufacturer’s instructions.
1�1�11 Bettis recommends that disassembly of the actuator modules should be done in a
clean area on a work bench.

Section 1: Introduction
Introduction
1�7 Fluid Requirements
1�7�1 For use in the hydraulic power module. The following listed uids are
recommended uids only and do not limit the use of other hydraulic uids
compatible with supplied seals and coatings.
1�7�1�1 Standard temperature service (-20°F to +350°F)/(-28.9°C to +176.6°C)
use Shell Tellus S2 V Grade 32 automatic transmission uid or an Emerson
approved uid.
1�7�1�2 High temperature service (0°F to +350°F)/(-17°C to +176.6°C) use
Shell Tellus S2 V Grade 32 automatic transmission uid or an Emerson
approved uid.
1�7�1�3 Low temperature service (-50°F to +150°F)/(-45.6°C to 65.6°C) use Mobil
Univis HVI 13 hydraulic uid or an emerson approved uid.
1�7�2 For use in the -H hydraulic override module and the M11 manual hydraulic
override system:
CAUTION: ONLY USE CORRECT FLUID
Hydraulic uid, other than listed in step 1.7.2.1 should not be used in the M11 Override or –H
Hydraulic Override Module without prior written approval of Bettis Product Engineering.
1�7�2�1 All temperature service (20°F to +350°F) / (-28.9°C to +176.6°C) use
Shell Tellus S2 V Grade 32 automatic transmission uid or an Emerson
approved uid.
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.

Section 1: Introduction
Introduction
1�10�2 Actuators are shipped from the factory with the travel stops adjusted for
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.
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
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.
NOTE:
Scale and debris can damage control valves, solenoids, seals, etc.
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.

Section 1: Introduction
Introduction
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
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.
