In 1996, our engineers began to develop and produce rack & pinion pneumatic actuators. After more than 30 years of technical accumulation and market test, our pneumatic actuators not only has excellent quality and more specifications, but also innovates a variety of new functions. In recent years, our engineers adopt the modular superposition design ideas, at the end of the traditional actuator integrated the sliding clutch mechanism and guide screw push and pull mechanism, the C-IMO series multifunctional pneumatic actuator is developed and produced with new functions such as manual operation, multi-stroke selection and multi-point limit.

Features & Benefits

√ Flexibly switch pneumatic and manual operations
√ The hand wheel or wrench can be used to open or close the valve
√ Available to setting up 3 pneumatic strokes (0 - 90°, 0 - 45°, 45 - 90°)
√ The start or end positions of the stroke can be flexibly set
√ Available to double acting and spring return
√ Certifided by CE SIL3 and ATEX

Pneumatic stroke between 0 to 90°

Adjust the position indicator of lead screw to the middle position through the handwheel or wrench, and the multifunctional pneumatic actuator can perform the 0-90° pneumatic stroke as follow,

Pneumatic stroke between 30 to 90°

Adjust the position indicator of lead screw to the 30° position of close limiter area by the hand wheel or wrench, and the multifunctional pneumatic actuator can perform 30-90° pneumatic operation as follows,

Modularization & diversity

Manual operation

The product model of the pneumatic actuator with integrated manual override from Wilson Flow Control Group confisits of five parts: series, size, acting type, working temperature and manual mode. Among them, the size refers to inner diameter of the body in the actuator.

How To order the IMO Actuator

Example for the part no.

1, C-IMO92DAT1H
The multifunctional pneumatic actuator is double acting and the size is 92 with hand-wheel and without locked device, the working temperature range is -15℃ ~ 150℃.
2, C-IMO210SR12T0WL
The size of the multifunctional pneumatic actuator is 210 equipped with 12 pcs springs for spring return with locked device and manual operation by wrench, the working temperature range is -20℃ ~ 80℃.

Operating Conditions

1) Operating media: dry or lubricated air, or non-corrosive gas filtered. The maximum particle diameter must less than 30um.
2) Working pressure: the pneumatic pressure of the actuator is from 2 ~ 8 Bar.
3) Operating temperature: T0: NBR O-ring, -20°~80°; T1: Viton O-ring, -15°~150°; T2: LNBR O-ring, -40°~80°; T3: LNBR-R O-ring, -50°~ +80°, T4: P-Silione O-ring, -60°~ +80° .
4) Travel and its adjustment: standard travel, 0°~ 90°, adjusting range, ±5° at 0° and 90° positions by screw bolts on the body. Adjusting and limit of the midway at any position within the range of 5°~ 85° by external hand wheel or limit adjusting plate.
5) Working environment: the standard coating (hard anodized for body and polyester coated for end-caps) is suitable for none-corrosive environment.The nickel phosphorus or PTFE coated are optional for application in a harsh and corrosive environment.
