2Rotork Actuators – Quality Controlled
Quality
RC200 actuators are manufactured under strict quality control in an ISO 9001 / 14000 environment. They comply with all standard international requirements and are CE marked according to PED and ATEX. We use only top-quality materials in a precisely engineered and manufactured product so our actuators are very long lasting. We are proud to provide a unique three-year warranty.
Efficiency Unlike rack & pinion designs often offered by our competitors, the RC200 with its scotch-yoke drive gives at least 50% more torque in the end positions, where most valves require it.
Reliability
Every Rotork Fluid Systems actuator is built to provide long
and efficient service with a minimum of maintenance. The
design, engineering and materials used in their construction
ensure optimum performance even in the harshest of
environments.
Remote Control Range RC200 Compact Scotch-Yoke Actuators Since the company was founded in 1957, Rotork
has become the standard for excellence in the
field of valve and damper automation for the
oil, gas, power, water and waste treatment
industries around the world.
As established leaders in actuation technology, we owe our
success to a commitment to quality at every stage, and at
every level, of Rotork's operations.
At the heart of the company is an exceptional workforce –
the highly trained, forward thinking engineers, technicians,
and sales support staff who each play a crucial role in
maintaining Rotork's unrivaled reputation for innovation,
reliability and first class after sale support.
With several fluid power factories and additional Centres
of Excellence located around the globe, we are able to
offer creative solutions and design systems for virtually any
application – from subsea hydraulics to the most sophisticated
yet simple fluid power control system.
Contact Rotork for your operational or safety application
requirements. We will work with you from conception,
to design, to manufacture, to installation, and finally to
maintenance and service support.
The Rotork Fluid Systems RC200 pneumatic actuator features
a modern scotch-yoke mechanism that provides high start- and end-torque output in a very compact package.
It is available in both double-acting and spring-return configurations with an optional integral manual override. Spring-return actuators feature springs that are safely contained within an epoxy coated cartridge. Pistons are guided in two places by high-performance bearings which ensure proper alignment and long seal life. Adjustable travel stops are available in both directions.RC200 actuators have the lowest weight and the smallest external dimensions of any actuator with an equivalent
torque output. This yields a compact and light yet robust valve / actuator package, particularly when a manual override solution is required. Another benefit is that they have less stroke volume than comparable rack and pinion actuators, providing a significant saving in the use of compressed air.

CE Marking: CE marked according to PED and ATEX.Features and Benefits
? For either on/off and modulating applications.
? Lightweight, compact design.
? Double-acting and spring-return configurations.
? Pre-tensioned springs for safety.
? High torque in the end-of-stroke positions.
? Connections and mounting according to
international standards.
? High efficiency, low air consumption.
? Housing in anodised aluminium.Note on the RC265 The RC265 size is an addition to the 200 series actuator family. This model was added as an optimum solution to a torque gap between the 260 and 270 sizes. It incorporates all the standard features of the RCI200 series except that it is available only in standard and high temperature builds. An added feature unique to the 265 model is adjustable limit stops that allow ±4° adjustment of both open and close positions. An external stop cam can be custom machined for different degrees of rotation.

Rotork Actuators – Quality Controlled
Compact Declutchable Handwheel
The override is integrated in the endcap of the actuator and
can be fitted to all RC200 series units in both double-acting
and spring-return configurations. The RC M1 manual override
is the optimum solution for users requiring a compact unit of
minimum weight and size.
? For both double-acting and spring-return actuators.
? Lightweight yet rugged design.
? Safe, non-rotating handwheel, eliminates use of levers
for manual operation.
? Valve/actuator can be locked in either open or close position.

With control accessories
See the comparison below of an RC200 M1 with a rack and pinion actuator equipped with an intermediate gearbox providing the override function. Note that the installed height of an RC200-DA with M1 override is the same as an RC200 actuator without manual override and is significantly less than that of an actuator/
gearbox solution.
