Building on Rotork’s historical success with

innovative technology, the CVQ offers a highly

accurate and responsive method of automating

control valves without the complexity and cost

of a pneumatic supply. With an increased focus

on production costs and efﬁciency, accurate

control of the process variable is paramount.

With resolution ﬁgures better than 0.1% and the ability to

eliminate position overshoot, the Rotork CVA range helps to

maximize product quality and plant capacity.

CVA range actuators are self contained, purpose designed

and built for continuous remote electrical operation of

control valves.

This Manual covers the Quarter Turn Control

valve Actuator Range (CVQ).

CVQ 1200 & CVQ 2400

Refer to Rotork Publication P110E for full specification.

The actuator comprises:

•DC brushless electric motor.

•Reduction gearing with quadrant output gear.

•Motor controller with speed, travel and torque limitation.

•Electronic logic controls and monitoring facilities housed

in a double sealed watertight enclosure.

•Hazardous area certiﬁcation meeting international and

national requirements.

All torque and position settings as well as conﬁguration of

the actuator are made using a non-intrusive Bluetooth device,

typically a PDA (not supplied).

Bluetooth™PDA software is available for free download from

www.rotork.com.

This manual has been produced to enable a

competent user to install, operate, adjust and

inspect the Rotork Range of Control Valve

Actuators.

The electrical installation, maintenance and use of these

actuators should be carried out in accordance with the

National Legislation and Statutory Provisions relating to

the safe use of this equipment applicable to the site of

installation.

For the UK: Electricity at Work Regulations 1989 and the

guidance given in the applicable edition of the ‘IEE Wiring

Regulations’ should be applied. Also the user should be fully

aware of their duties under the Health and Safety at Work

Act 1974.

For the USA: NFPA70, National Electrical Code®is applicable.

The mechanical installation should be carried out as

outlined in this manual and also in accordance with any

relevant national standard codes of practice. If the actuator

nameplate indicates that it is suitable for use in a Potentially

Explosive Atmospheres (Hazardous Areas) then the actuator

is suitable for use in Zone 1 and Zone 2 (or Div 1 and Div 2)

hazardous area classiﬁcations, as deﬁned by the actuator’s

nameplate marking.

Any equipment connected to the actuator should be of

an equivalent (or better) hazardous area certiﬁcation. The

installation, maintenance and use of the actuator installed in

a hazardous area must be carried out by a competent person

and in accordance with all relevant codes of practice for the

particular Hazardous Area certiﬁcation.

Any inspection or repair of Hazardous Area approved

actuators should not be undertaken unless it conforms to

National Legislation and Statutory Provisions relating to the

speciﬁc Hazardous Area. Only Rotork approved actuator

replacement parts should be used. Under no circumstances

should any modiﬁcation or alteration be carried out on the

actuator, as this could invalidate the conditions under which

its certiﬁcation was granted.

Access to live electrical conductors is forbidden in a

Hazardous Area unless it is done under a special permit

to work, otherwise all power should be isolated and the

actuator moved to a non-hazardous area for repair or

attention.

Only persons competent by virtue of their training or

experience should be allowed to install, maintain and repair

Rotork actuators. Work undertaken must be carried out in

accordance with instructions in the manual. The user and

those persons working on this equipment should be familiar

with their responsibilities under any statutory provisions

relating to the Health and Safety of their workplace.

Enclosure Materials

The enclosures on the Rotork Range of Control Valve

Actuators are manufactured from aluminium alloy with

stainless steel fasteners and a polycarbonate window. The

Local Control Knob and Manual Override Knob (when ﬁtted)

are manufactured from a Polycarbonate/PBT plastic blend.

There is a potential electrostatic charging hazard associated

with these components and therefore they must only be

cleaned with a damp cloth.

The user must ensure that the operating environment and any

materials surrounding the actuator cannot lead to a reduction

in the safe use of, or the protection afforded by, the actuator.

Where appropriate the user must ensure the actuator is

suitably protected against its operating environment.

Should further information and guidance relating to the safe

use of the Rotork Control Valve Actuator Range be required,

it will be provided on request.
