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 modes respectively.

The actuators may be fitted with a variety of springs in order 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 five inches of travel.

Available options:

• Top or Side Mounted Handwheel
• Travel Stops
