Rotork is the world leader in the field of heavy duty actuators, systems and services for motorisation and manual operation of adaptions, industrial valves and dampers.
IQ Multi-Turn Actuator
-
The second generation of intelligent, non-intrusive, user friendly, electric valve actuators
-
Rugged, re-styled double sealed enclosure, impervious to the most demanding environments
-
Rotork Lifetime Care facility provides real-time, on-line troubleshooting, irrespective of global location
-
Secure `point and shoot` commissioning and interrogation, with or without mains power
-
Seamless interface with Profibus, Foundation Fieldbus, Modbus and Rotork Pakscan
-
Suitable for industrial valves of virtually every size and description
-
Modulating version IQM specification is generally the same as that of the type IQ, but with a solid state reversing starter in place of the electro-mechanical contactors, suitably rated 4-pole winding low inertia motor and with the `hammerblow` backlash omitted from the output gear train. The IQM is suitable for up to 1200 starts per hour with a duty in accordance with IEC 34-1 to S4 50%.
Features
Rotork`s tried and tested range of IQ electric valve actuators is now further enhanced - retaining legendary features such as Rotork`s unique double sealing system and `non-intrusive` infra-red commissioning capability whilst delivering a host of new innovations designed to make life easier for all engineers involved in the business of flow control.
IQT Quarter-Turn Actuator
-
Intelligent, non-intrusive quarter-turn actuator, incorporating all the benefits of standard IQ control and indication features
-
Suitable for 3 phase, single phase and 24V DC power supplies
-
Operating speed can be varied
A/M
`A` Range Syncroset
`A` Range Syncroset actuators combine the qualities of a robust electric motor and a well proven and simple mechanical drive. In addition, total environmental sealing and Rotork`s positive attitude to quality, result in an actuator of the utmost reliability.
`M` Range Syncroset Modulating Actuators
Type `M` multi-turn modulating actuators are available for use with separately mounted reversing starters based on the syncroset specification `A` Range design.
AQ - Electric, Direct Drive, Quarter Turn Actuators
Features
-
DC, single or 3 phase power supplies
-
Secure, self-locking drives, suitable for butterfly valves and dampers, without the use of additional brakes
-
Available with a watertight enclosure to IP68 (NEMA 4 & 6), or with a flame-proof (explosion proof) and watertight enclosure to IP68 (NEMA 4 & 6)
-
Externally adjustable mechanical output stops are provided, with a setting range of 80° - 100° of movement. The setting of these provides travel limitation for both electrical and manual operation.
-
The `AQ` actuator is designed to `torque off` at each end of travel, against it`s adjustable, mechanical stops. This feature enables adjustment of travel limits, without removing electrical covers
Q - Single Phase Electric Direct Drive Valve Actuators
Features
-
The `Q` range is a single phase, electric actuator which is available in two versions, both with the Rotork `double sealed` IP68 enclosure
-
The `Q` standard version is suitable for simple open/close duties, where on/off control is required. This is achieved without the need for reversing contactors, giving simplified wiring. The design of the motor and limit switch mechanism, ensure combined ease of setting and reliability in use
-
The `Q` – Pak version benefits from the addition of a specially designed control interface module, which enables it to operate from a wide variety of remote control signals and provides status monitoring outputs
-
Reliability of single phase, squirrel cage motors
-
Simple remote control for basic applications
-
Rugged, compact, double sealed, watertight enclosure, providing environmental protection during plant construction and cabling
-
Positive travel limitation by externally adjustable mechanical stops
Skilmatic Range
Rotork Skilmatic Linear and Quarter turn actuators are compact and robust, self-contained electric units, for both modulating and two-position control, of all types of valves and dampers. They are also suitable for adjustable slow-opening applications and ESD quick closure.
The actuators combine the simplicity of electrical operation, with the precision of hydraulic control and the reliability of spring-powered, fail-safe action.
Rotork Skilmatic actuators use an internal spring-return mechanism to provide the most reliable means of positioning a valve in a safe condition. They can be fail-safe to close or open, or lock in position on power or system failure.
With both weatherproof and flameproof models, the range simplifies process automation, by providing true electronic control from process variable to valve and supplies a totally electric system for all environments.
The unit can be supplied with the appropriate electronic controls to match any process control system requirement.
Features
-
Self contained electrically operated
-
Spring-powered fail-safe action
-
Rotork Skilmatic internal digital electro-hydraulic control
-
Simplicity of design

Serial Communications
A serial communication network using 2, 3 or 4 wires to the actuator can greatly reduce the installed cost of each actuator and provide extensive actuator and valve condition information to the maintenance staff and control room operators.
Features
-
Increases operator information and confidence
-
Maintenance and diagnostic data available
-
2, 3 or 4 wire bus system options using open protocols
-
Rotork Pakscan 2 wire system for field cable protection
-
