Pneumatic Actuators

Advantages of pneumatic actuators include speed of response, quick cycle times, and ease of air compression.

Torque is derived from area in an air cylinder and pressure ( pressure X’s area = force ) to cycle valves 90 degrees ( called quarter turn ) or linear ( up and down movement ).

Advantages of pneumatic actuators ( compressible fluid ) can be speed of response / quick cycle times, compressed air easily sourced, no toxic fluids- environmentally friendly. Positioners are used for control and or throttling requirements.

Filter/Regulators & solenoids are typically specified for a complete package. Actuator springs can be used to make the actuator fail open or closed on loss of air pressure, ESD-explosion proof applications-others. Concerns can be moisture that could freeze making equipment non-working.
