General Information

GENERAL ACTUATOR DESCRIPTION

Building on Rotork’s historical success with innovative
technology, the CMA offers a highly accurate and responsive
method of automating control valves and pumps without the
complexity and cost of a pneumatic supply.

With a minimum resolution of 0.2% of full stroke for Linear
& Quarter-turn units and 0.6% of full stroke for Multi-turn,
the Rotork CMA range helps to maximize product quality
and plant capacity.

CMA range actuators are self contained, purpose designed
and built for continuous remote electrical operation of
control valves.

CMA range of actuators delivers a series of sizes suitable
for almost all linear, quarter- turn and rotary control valve
and pump applications requiring exact position control and
unrestricted continuous modulation.

Refer to Hazardous Area Approval section for further detail
concerning approved actuators

CML - Linear

The CML is a high precision linear actuator. It is capable of
producing up to 750 pounds of force and a maximum of 2
inch stroke length at a speed of up to .063 inches per second.

NOTE: Thrust and Speed are dependant on frame size.

See page 7 for full details.

CMQ - Quarter-Turn Actuators

The CMQ is a high precision quarter-turn actuator capable
of producing between 250 to 1000 inch pounds at speeds
between 10 to 22 seconds 90 degree operating times.

NOTE: Torque and operating times are dependant on
frame size.

See page 7 for full details.

CMR - Rotary

The CMR is a high precision rotary unit with torque outputs
between 50 to 250 inch pounds at output speeds between
5 to 12 RPM depending on frame size.

NOTE: Torque and operating times are dependant on
frame size.

The actuator comprises:

• Absolute Encoder

• LCD User Interface

• DC brushless electric motor

• Simple, maintenance free geartrain

• Motor controller with travel and

torque/thrust adjustment

1 Encoder Technology

The CMA utilizes absolute encoder technology where a
unique digital code corresponds to the angular position
(CMQ), stroke length (CML) or rotary (CMR) position of the
actuator.

To achieve high resolution, the position sensor location
eliminates any backlash effect in the gearing. The sensor is
a 12-bit rotary magnetic encoder, fitted at the output gear
stages, removing any internal backlash effect that may exist in
the drive train.

2 User Interface

The CMA LCD display is a 6-character, single line display.
Two graphic symbols are provided for notification of alarm
conditions. The menu style is an intuitive common tree
structure similar in function to the menu system used on PCs.

Two relays can be programmed to close upon reaching a
desired position or any other available fault condition among
the programmable options.

3 DC Brushless Motor

The CMA uses a high efficiency, continuous rated, brushless
DC motor. This allows maintenance-free operation even with
continuous unrestricted modulation duty.

4 Hand Drive

A hand drive mechanism is provided as standard for all CMA
actuators to allow manual operation of the valve. Pressing
down on the hand-knob shaft allows it to engage a gear
in the upper section of the drive train. Releasing causes the
spring to disengage the gear.

5 Geartrain

The simple yet durable high efficiency spur gear drive is
lubricated for life. It has proven high reliability.

The CML and CMQ standard build is capable of resisting any
back drive from the load, up to 125% of the rated thrust or
torque of the actuator.

6 Output Drive

The CMQ base conforms to MSS SP-101 or ISO5211.
The CMR and CML may be adapted to suit individual valves.

General Information

Mechanical Performance

The rated force (thrust or torque) for each size of actuator is
detailed below. The minimum settable force is 40% of the
maximum rated. Operating time tolerance +/-10%.

The CML and CMQ can resist backdriving forces from the
valve up to 125% of rated load without movement.

CML: Linear Actuator

Vibration, Shock and Noise

CMA actuators are suitable for applications where vibration and shock severity does not exceed the following:

Type Level

Plant induced vibration

1 g RMS total for all vibration within the frequency range of 10 to 1000Hz.

Shock 5 g peak acceleration.

Seismic 2 g acceleration over a frequency range of 1 to 50 Hz if it is to operate during and after the event.

5 g over a frequency range of 1 to 50 Hz if it is only required to maintain structural integrity.

Emitted noise

Levels quoted are those present at the actuator mounting interface. It should be noted that the effects of vibration are cumulative and therefore an actuator
subjected to significant levels may have reduced life.

Independent tests have shown that at 1 m generated noise does not exceed 61 db (A).

Mounting the Actuator

Move Valve stem to the closed position

To enable the actuator to be installed correctly the valve must
be in the closed (down) position to allow fitting of the valve
stem/actuator coupling.

Actuator Output Shaft

The actuator is supplied with the output shaft in the fully
retracted position. If the output shaft is in the extended
position it may be necessary to manually operate the actuator
using the hand wheel to the retracted position to allow
installation. Push and turn the hand wheel to retract the
output shaft.

Fig. 16.1

Valve Stem Coupling

Machine the valve stem to actuator output shaft coupling
adaptor to suit. (NOT SUPPLIED)

Fit the coupling to the valve stem. It may be necessary to use
a locking nut to eliminate any backlash.

Leave the coupling loose and free to rotate at this stage.

CML-100 & CML-250 Units Only

Remove the locking ring from the base of the actuator and
position the unit on to the valve mounting flange.

CML-750 Units

Fig. 16.4

Mounting the Actuator

Replace the locking ring.

DO NOT FULLY TIGHTEN AT THIS STAGE.

Extend the actuator output shaft to bring the end of the shaft
and the coupling together. Rotate the coupling as required
to get a good firm contact between the valve stem and the
output shaft.

Adjust and tighten locking nut(s) if fitted on valve stem side of
the coupling. Ensure that the actuator is centrally aligned with
the valve stem.

If the actuator output shaft reaches its fully extended position
it will be necessary to retract the actuator shaft a sufficient
distance to allow adjustment of the coupling to ensure a tight
shut off in thrust seating valves.

Mounting the Actuator

CMQ - QUARTER-TURN UNIT - MOUNTING

CAUTION

It is essential that mounting procedure is carried out
when the valve is not under working process conditions,
as full valve movement may occur.

IMPORTANT

It is essential that the actuator is mounted correctly to
the valve, damper or other device.

The Installation & Setup will include the following procedures:

1. Prepare the Drive Coupling.

2. Ensure Valve position is noted and safe (Offline).

3. Mount and align actuator to valve.

4. Adjust Actuator Stop Bolts.

5. Carry out Basic Setup.

ACTUATOR STOP BOLTS

The Quarter-turn CMQ actuators have two end of travel stop
bolts adjustable between 80 to 100 degrees of travel rotation.

The Stop Bolts are set to a nominal 90 degrees of travel at
the factory. These must be adjusted to suit the required valve
travel BEFORE attempting to set the electrical travel limits.

The Clockwise end of travel stop bolt is on the right as viewed
in Fig. 18.2.

Mounting the Actuator

Securing Actuator to Valve

Before fitting actuator to the valve ensure that the actuator
and valve are in the same position. The position of the
actuator can be confirmed by using the hand wheel

A suitable mounting flange conforming to ISO 5211 or USA
standard MSS SP-101 depending on the actuator supplied
must be provided to mount the unit to the valve top works
assembly.

Actuator to mounting flange assembly fixings must conform
to Material Specification ISO Class 8.8. Delta GZ coated Grade
A4 stainless steel fixings are recommended.

Actuator is supplied with a square output drive shaft. A
coupling and adaptor bracket is required to mate the actuator
to the valve stem.

Fig. 19.3 shows a typical valve adaptation kit.

Fit suitable mounting brackets and adaptors to the valve body.

Ensure that valve stem and actuator output shaft are in the
same position (Open or Closed).

Align the actuator output shaft with stem adaptor

Position actuator on to the valve mounting flange. It may be
necessary to adjust the position of the actuator to enable
alignment of the fixing bolts.

Tighten base fixings in accordance with table 2.

Stop Bolt Adjustment

It is recommended that stop bolt adjustment be carried out
by the valvemaker/supplier before the valve is fitted in to the
pipework.

Once installed the valvemaker/supplier should be consulted
before stop bolt re-adjustment is carried out. After setting or
adjustment of stop bolts the actuator limits must be reset.

The CMA stop bolts are located on the lower body assembly.
The stop bolt adjustment allows +/- 5
each end position. Screwing bolts in reduces the range of
movement, out increases range of movement.

For clockwise closing valves the right hand bolt is the closed
stop as shown in Fig 20.2. The left hand bolt is the open stop.

Stop bolts are factory set to give a nominal travel of 90
degrees travel.

Adjustment for non seating valve types

For closed and open stop position adjustment. Undo stop bolt
locknut. Move actuator and valve to the required stopping
position (it may be necessary to unscrew stop bolt to allow
more travel). Screw stop bolt in until a stop is felt. Tighten
stop bolt lock nut.

The Installation & Setup will include the following procedures:

1. Prepare the Drive Coupling.

2. Ensure Valve position is noted and safe (Offline).

3. Mount and align actuator to valve/pump.

4. Carry out Basic Setup.

A suitable mounting flange must be provided to mount
the unit to the valve top works assembly. Mounting flange
assembly fixings must conform to Material Specification ISO
Class 8.8. Delta GZ coated Grade A4 stainless steel fixings
are recommended. CMA Rotary actuators are supplied
with base assembly suitable for Non Thrust applications
requiring between 180 degrees and 320 turns operation.
For applications that require thrust to be taken by the actuator
apply to Rotork Process Controls.

Drive Coupling

Machine and fit coupling adaptor to the actuator output shaft
and secure appropriately.

Align and Mount Actuator

Ensure that the actuator/stem coupling is aligned correctly
with the stem of the valve or actuated device. Mount the
actuator to the flange adaptor, ensure that the actuator is

After the open/close limit is set the 4 to 20 mA signal is
automatically calibrated to those positions. The 4 mA input
command will send you to CLOSED LIMIT, the 20 mA and will
send you to OPEN LIMIT.However to calibrate to field signal
follow page 38.

BASIC SETUP

The CMA proportional controller enables the actuator
to automatically position a valve or actuated device in
proportion to an analogue mA current. A signal derived from
the actuator position feedback is compared with a signal
proportional to the input signal. The difference (error) is used
to energize the motor and drive the output to the required
position to cancel the error.

Unwanted frequent operation can be prevented by
adjustment of the deadband.

NOTE: The 4 mA command signal is automatically
referenced to the fully closed limit position. If necessary
reverse the limits of travel to achieve the desired
