Identification
The BETTIS™ RPE-series Rack and Pinion actuators are available as double-acting or
spring-return versions. 13 models are available, ranging from 23 Nm to 4041 Nm
(206 to 35765 lbf.in)nominal torque output.
The Bettis RPE-series uses standardized interfaces for solenoid, switchbox or positioner
mounting (VDI/VDE3845; NAMUR). The valve interface is equipped with an insert in the
pinion bottom that allows both ISO5211 or DIN3337 mounting.
The springs in the spring-return version allow a fail action in case of loss of air supply
pressure (Fail-to-Close or Fail-to-Open).
As from size RPED150 double-acting versions have flat end caps to reduce actuator length
and internal air volume.

4.3.2
Ingress Protection (IP) rating
Bettis RPE actuators are IP66/IP67 rated. In case of IP66 or IP67 requirements, take
precautions that comply with the IP66/IP67 requirements to prevent moisture or dust from
entering the actuator through the open air exhaust port(s), either directly on the actuator
or at the exhaust ports of the connected solenoid valve.
We recommend to connect tubing to the exhaust(s) and lead this into a dry and dust free
area, or to use check valves in the exhaust.

Double-Acting Actuators
The operating principle, as explained here, is applicable for actuators with assembly code
CW (direct acting).
•
Applying supply pressure to port A will move the pistons outward to the "Open"
position of the valve.
•
Applying supply pressure to port B will move the pistons inward to the "Close"
position of the valve.
•
For assembly codes CC, the operating principle is reversed (reverse acting).

Spring-Return Actuators
The operating principle, as explained here, is applicable for actuators with assembly code
CW (direct acting).
•
Applying supply pressure to port A will move the pistons outwards to the "Open"
position of the valve.
•
Venting the supply pressure from port A will cause the springs to move the pistons
inwards to the "Close" position of the valve.
•
For assembly codes CC, the operating principle is reversed (reverse acting).

Actuator to Valve Installation
WARNING MOVING PARTS
Actuator must be isolated pneumatically and electrically before any (dis)assembly starts.
Stay away from moving parts to prevent serious injuries. When test cycling the actuator
and valve assembly by applying pressure to the A or B port, be aware that there are moving
parts like pinion top, actuator to valve coupling and the valve- blade, ball, plug, etc.
NOTICE
The actuator is designed to be installed, commissioned and maintained using generic tools
like wrenches, Allen keys and screwdrivers. For the removal of inserts, a special extractor
tool can be supplied on request.
During assembly to the valve, do not hit with hammer on pinion top. This can damage the
pinion top washer and cause premature failure.
Before mounting the actuator on the valve or valve bracket, be sure that both the
actuator and the valve are in the same closed or open position.
Refer to appendix B, Tool and Torque tables, for using the right size tool

Section 5:Mechanical Stroke Adjustment
This section explains:
•
What mechanical stroke adjustment is.
•
What the factory settings are.
•
How to adjust the travel stops.
Bettis RPE actuators have two stroke adjustment stops for adjusting accurately the stroke
of the actuator/valve assembly in open and closed position.
The factory setting of the stroke is 90°. Most quarter-turn valve applications will not require
readjustment of these settings.
If required the stroke can be adjusted by means of two-stroke adjustment bolts.

6.1
Normal Maintenance
Bettis RPE actuators are designed to operate without maintenance for their normal
working life. Normal working life is 500,000 cycles.*
We recommend regular inspections to make certain that the actuator / valve assembly
operates smoothly and to check that there are no visible or audible defects. We advise to
perform the following checks upon each proof test interval complying with the rules and
regulations of the country of final installation:
20
•
Visually check the entire actuator as well as the control system (where foreseen).
•
Ensure there are no leaks on the actuator parts under pressure.
•
Check pneumatic connections for leaks. Tighten tube fittings as required.
•
Check if manual override (where foreseen) is regular.
•
Check if pneumatic filter cartridge (where foreseen) is sound and filter bowl
(where foreseen) has been cleaned properly.
•
Check the setting of the relief valves (where foreseen).
•
Verify that the power fluid supply pressure value is within the required range.
•
Remove built-up dust and dirt from all actuator surfaces.
•
Inspect actuator paint work for damages to ensure continued corrosion protection.
Touch-up as required in accordance with the applicable paint specification.
•
Operate the Actuator/Valve assembly for No 2 open/close complete cycles with
complete closing of the valve.
•
Verify the correct performing of open – close operations (e.g. check locally,
or automatically via Logic solver, the correct movement of the actuator).

7.1
How to decommission an actuator in a safe way.
Before You Start
WARNING - MOVING PARTS
Actuator must be isolated pneumatically and electrically before any (dis)assembly starts.
Before mounting or (dis)assembling the actuator consult the relevant sections of this manual.
Actuator can move when removing supply pressure and/or electrical control signal of
actuators. If not already there, a spring-return actuator will cycle to its fail position.
When removing any ball valve or plug valve assemblies from a pipe system, isolate the
piping system on which the Actuator is installed and relieve any media pressure that may
be trapped in the valve cavities before removing the actuator for maintenance.
A spring-return actuator mounted on a valve, which is stuck in mid stroke, contains a
high spring load which will cause a sudden rotation of the actuator versus the valve or
valve bracket during disassembly. This can cause serious injury to personnel or damage
to property.
Refer to Appendix A for instructions to safely remove the spring load before disassembling
the spring-return actuator from valve or bracket.
Important
Refer to the Safety Guide for Lifting Instructions.

How to disassemble an actuator safely.
Tip
The instructions of this section can be used for maintenance or reconfiguration like spring
set change or maintenance.
Reference numbers for components refer to the exploded view in section 11.
In case of maintenance, discard all the used soft parts like O-ring seals, guide bands,
wear strips and circlip.
WARNING
Actuator must be isolated pneumatically and electrically before any (dis)assembly starts.
Before mounting or (dis)assembling the actuator consult the relevant sections of this manual.
CAUTION - PRESSURIZED ACTUATOR
Spring-return actuators contain springs in a compressed state. Follow these instructions to
release the spring force safely.
Normally the end caps of spring-return actuators should be free of the spring load after
10 full turns (crosswise relaxing) of the end cap screws. If there is still spring load on the
end cap, this might indicate a broken spring cartridge. Stop this disassembly procedure
immediately. Continuing might cause the end cap to be “shot” away causing serious injury.
Refer to Appendix A for instructions to safely remove the spring load before disassembling
the end cap of a spring-return actuator with a broken spring cartridge.
NOTICE
The actuator is designed to be installed, commissioned and maintained using generic tools
like wrenches, Allen keys and screwdrivers.
Refer to the tables in this section or refer to appendix B Tool and Torque tables.

Appendix A: Spring load removal
This section explains:
•
How to remove the spring load safely of spring-return actuators in case:
——
The valve gets “stuck” in mid position.
——
One of the spring cartridges is broken.
WARNING - MOVING PARTS
A Spring-return actuator mounted on a valve, which is stuck in mid stroke, contains a high
spring load which will cause a sudden rotation of the actuator versus the valve during
disassembly. This can cause serious injury to personnel or damage to material.
On Spring-return actuators with a broken spring cartridge, the end cap can be “shot” away
during disassembly of the actuator. This can cause serious injury to personnel or damage to
material.
A.1
Spring load relief
CAUTION - ROTATING ACTUATOR
In case of an actuator/valve assembly “stuck” in mid position, leave the actuator on the
valve and/or mounting bracket during this procedure.
Figure A-1
Spring load removal
WARNING
Crush / Amputaion Hazard
Failure to follow instructions
for removal of spring loaded
actuator may result in
surious personal injury
Appendix
1.
Depressurize the actuator completely.
2.
Based on the actuator size, choose the correct threaded rod kit from Table A-1.
3.
Replace one by one each end cap screw for the threaded rod kit and turn down the
adjusting nut until it touches the end cap.
4.
Once all for end cap screws have been replaced, gradually turn the adjustment nuts
on threaded rod in CCW direction by turning the nuts half turn at a time. Make sure
the rod itself does not turn. Continue this until the load of springs are relieved.
5.
Repeat the same procedure for the end cap screws on the other size of the
actuator as shown in figure A-1.
6.
In case of an actuator/valve assembly “stuck” in mid position: The actuator now
can be disassembled from Valve, by removing the mounting studs / bolts.
