Compact Low Profile
With the specially designed flat-top bonnet, the Century actuator provides a strong, totally enclosed unit with extremely low over-all height.

Wide Selection
Actuators furnished in seven sizes to provide more efficient and economical use of available operating air pressures up to 200 psig.

Longer Strokes
Together with higher air pressure capability provides greater flexibility in valve/actuator selection. Example, the No. 0 (smallest actuator) has more than double the stroke of its nearest competitor.

Lower Air Consumption
Because of unique design, air consumption is extremely low - in most instances less than half that of competition.

Adjustability
In the spring-closed actuator, the adjusting screw provides a convenient means of obtaining valve closure when line pressures are higher than expected.

Adaptability
Suitable for either pneumatic or hydraulic operation, the unit can be mounted in vertical, horizontal, or any intermediate position.
