Pneumatic actuator power signal range

Pneumatic actuator is a device that drives valves through pneumatic pressure, which can achieve the opening and closing or regulating functions of valves. Pneumatic actuators typically consist of an air chamber, a diaphragm, a spring, and a valve stem. The air pressure inside the chamber can be adjusted through control signals to change the shape and position of the diaphragm, which in turn drives the valve stem to move and achieve valve control.

The power signal range of pneumatic actuators refers to the pressure range of the control signal, that is, the pressure range inside the chamber. Different pneumatic actuators have different power signal ranges, generally between 0.2 and 1.0 MPa. The size of the power signal range will affect the output force and sensitivity of the pneumatic actuator. Output force refers to the strong force that pneumatic actuators can apply to valves, while sensitivity refers to the response speed and accuracy of pneumatic actuators to changes in control signals.
Generally speaking, the larger the range of power signals, the greater the output force, but the lower the sensitivity; On the contrary, the smaller the range of the power signal, the smaller the output force, but the higher the sensitivity. Therefore, when selecting pneumatic actuators, it is necessary to comprehensively consider the suitability of the power signal range based on factors such as valve type, specifications, and working conditions.
