Actreg act 80r pneumatic actuator

What is the ACTREG ACT 80R Pneumatic Actuator?

The ACTREG ACT 80R is a rack-and-pinion type of pneumatic actuator that translates compressed air energy into mechanical motion in order to drive quarter-turn valves, like ball valves and butterfly valves. This actuator guarantees quick and dependable valve operation, making it a great fit for industries that need precision and efficiency.

It is offered in both double-acting and spring-return types, allowing for flexibility depending on various industrial requirements.

How Does the ACT 80R Pneumatic Actuator Operate?

The ACT 80R actuator functions on the pneumatic principle, wherein compressed air is employed to generate linear or rotary motion. Here is how it works:

Air Supply & Motion Generation:

• Compressed air is fed into the actuator, driving the internal pistons apart (in double-acting types) or winding return springs (in spring-return types).
• This motion is transferred to a rack-and-pinion mechanism that turns the output shaft.

Valve Operation:

• The rotary motion of the output shaft is utilized to open or close the valve.
• In a double-acting actuator, air is fed to both sides of the pistons for movement in both directions.
• In a spring-return actuator, the pistons are pushed by compressed air in one direction and are returned to the original position by pre-loaded springs when the air is withdrawn.

Position Feedback & Control:

• The actuator may be fitted with position indicators, limit switches, and solenoid valves for remote control and automation.
