A valve actuator is the mechanism for opening and closing a valve. Manually operated valves need someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. To begin with, valve actuators are a type of control valve.
Put simply, an actuator is a mechanical device that moves another device to serve a purpose. For example, TV lifts use an actuator to move the TV. It is, in the simplest of terms, the ``mover''.
Nowadays, the AHU actuator valves can be controlled automatically, without any manual task to run, by using an actuator device. These actuators receive the input from the AHU controller which determines how to regulate the passage of the flow, and apply pressure with their torque to action the valve.what is a pneumatic actuator
Examples of pneumatic systems and components
Air brakes on buses and trucks.
Air brakes on trains.
Air compressors.
Air engines for pneumatically powered vehicles.
Barostat systems used in neurogastroenterology and for researching electricity.

As a part of a pneumatic circuit, a flow control valves function is to reduce the rate of flow in a specific section, which then results in a slower actuator speed. It's designed so that the air will flow in one direction, which in turn, allows free flow in the opposite direction.
Pneumatic systems capture air and lower its volume as it moves around a circuit, compressing it to provide energy for industrial systems as well as everyday objects.pneumatic fitting size chart
A valve actuator is the device that [actuates"-or moves-a valve open or closed. It attaches to and works in conjunction with two parts: the valve body and the valve pilot.pneumatic fitting types
Maintenance- Pneumatic systems are less durable that hydraulic counterparts. Due to moisture accumulation the system can freeze up. Loudness: Pneumatic systems are the loudest type of designs that power machines.
Data management: sensor technology can generate large amounts of data, and managing, processing and analysing it can be a challenge for many manufacturers. 3. Complexity: Sensor technology can be complex and difficult to implement, especially for manufacturers with limited technical expertise.
One common example of a pneumatic actuator is the pneumatic cylinder. This type of actuator consists of a cylindrical chamber with a piston inside it, which is connected to a rod that extends out of one end.
