Pneumatic Actuators

K-Tork Range Actuators

DESIGN FEATURES:

K-TORK Actuators + Controls represents the future of valve automation. The vane actuator is a ‘True Rotary’ actuator that does not require the conversion of a linear motion to a rotary motion. The result is a simple, highly accurate and reliable quarter-turn pneumatic actuator that is specified for the most demanding process flow control applications.


Variants:

Standard, Air Fail-Safe (AFS) Range, Hand Wheel Manual Override Range, Ranger Corrosion-Guard (CG)

Remote Control Range RC200 / RCI200 Actuators

DESIGN FEATURES:

The RC200 is an extremely compact pneumatic actuator. Its scotch yoke design is particularly suited for valves with high start or end torque requirements. It is available in double-acting and spring-return configurations with torque output up to 4,400Nm (38,700 lbf-in). The RC200 is available in a variety of configurations and an extensive range of options and accessories is available.


Variants

Standard, RCC200 Steel Cylinder, RC200 Firesafe, RC88 High Torque, RCR 180°, RC200 Dosing Actuator

CP Range Actuator

DESIGN FEATURES:

CP range pneumatic actuators are a versatile, modular, scotch yoke design available in both double-acting and spring-return configurations. The compact and efficient design yields high torques even at low pressures. The design concepts found in Rotork's large, heavy-duty actuators has been applied to the CP range, which brings heavy-duty actuator qualities to small, quarter-turn actuators. The actuator body is of rugged, ductile cast iron available in four body sizes. Cylinders are manufactured from carbon steel, electroless nickel-plated.

GP Range Actuator

DESIGN FEATURES:

GP (pneumatic) range scotch yoke actuators are designed to provide a rotary, quarter-turn movement for either on/off or modulating duty. The rugged yet compact design is available with two different yoke designs. The classic symmetric yoke delivers peak torque at both ends of stroke. Alternatively, they can be supplied with canted torque arms designed to deliver peak torque at only one end of stroke. Use of canted arms can often reduce actuator size, weight and cost for valves with appropriate torque demand characteristics.

LP Range Actuators

DESIGN FEATURES:

Rotork linear actuators offer the advantages of compact size, high performance and a simple but highly reliable design. They are ideal for operating on/off and control functions of both globe and wedge gate valves. Both spring-return and double-acting configurations are available with either pneumatic or hydraulic cylinders.

Dezurik G-Series Cylinder Actuator

DESIGN FEATURES:

G-Series Actuators are available on large butterfly and plug valves where constant high torque capability throughout the stroke is required. They feature a rack-and-pinion design and are engineered for high-flow, high-cycle applications. They are available with either manual, cylinder or motor actuator input. The G-Series line of actuators provides a long service life and features a rugged, heavy cast gear sector. Multiple bronze and stainless steel bearings provide support and minimize friction to assure smooth operation and throttling action.
