Description. Product Name: Pneumatic Diaphragm Actuator. Type: Spring return diaphragm. Action: Reverse acting or direct acting. Supply air pressure: 260 to 800 kPa. Air connection: 1/4 NPT or 3/8 NPT ...

Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. There are two main forms: the piston actuators and diaphragm actuators. Piston actuators are ...

[Richard Sewell] decided to investigate. The result is a pneumatic actuator built out of lasercut acetal parts. The mechanism consists of of two outer layers of plastic acting as the enclosure ...

Describe how these forces work in the positioning of closure components. Prepare equations required to determine an actuator (i.e. pneumatic, hydraulic, or electric) size based on piston or effective ...
