700 Series: Pneumatic Diaphragm Actuator

Series 700 actuators are pneumatic diaphragm operators that offer spring return in either direct or reverse acting styles, offering fail-open and fail-closed models respectively.

The series 700 actuators may be fitted with a variety of springs to overcome the wide range of forces that may exist on a valve plug. An adjusting mechanism is incorporated into the actuator design to allow for adjustment of the spring pre-compression.

The series 700 actuator is available in 60, 100 and 160 square inches of effective diaphragm area and may accommodate up to 5 inches of travel.

1000 Series: Pneumatic Diaphragm Actuator

Designed specifically for severe duty service, series 1000 actuators can be used in any application where shock and/or vibration may be encountered. Model 1000 actuators have undergone extensive testing and analysis for seismic and environmental considerations and are suitable for nuclear applications. Series 1000 actuators have undergone extensive testing and analysis for seismic and environmental considerations and are suitable for nuclear applications.

Series 1000 actuators are available with 60, 100, 160, 320 and 400 square inches of effective diaphragm area and may be supplied as either direct or reverse acting.

P800 Series: Pneumatic Piston Actuator

Series 800 actuators are pneumatic piston operators that are available in spring opposed direct and reverse acting models or a springless double acting configuration.

The series 800 actuator ranges from 4 to 44 inches in diameter with an available travel of up to 15 inches. The direct and reverse acting models may be fitted with a variety of springs to overcome the wide range of forces that may exist on a valve plug.

Viton seals are available for high temperature applications or environments with radiation exposure.
