The role of positioners in valve control is to ensure that the assigned valve position, or controlled variable x, corresponds to the reference variable w. In order to accomplish this, positioners compare the input signal from a control system to the travel of the control valve. The resulting output signal pressure pst, or output variable y, is adjusted accordingly.
In the case of double-acting actuators, a reversing amplifier is necessary to produce two opposed signal pressures. This ensures that the valve position can be adjusted in both directions as required.
The use of positioners in valve control systems is crucial for ensuring accurate and reliable operation. Without proper positioners, valves may not be able to maintain their assigned position, leading to issues such as leaks, inefficiency, or even equipment failure.

There are two types of positioners that can be used for pneumatic control valves: single-acting and double-acting. These devices are attached to the valve and work to ensure that it is adjusted to the right position.
Single-acting positioners use air pressure to move the valve either to an open or closed position. They are typically less expensive than double-acting positioners and are ideal for simple applications where fast response times are not necessary.
On the other hand, double-acting positioners are generally more expensive but offer greater accuracy and faster response times. They use both air pressure and a spring to move the valve and can adjust to a range of different positions.
Regardless of which type of positioner is used, they are essential components in pneumatic control valve systems. They ensure that the valve is properly adjusted, which in turn helps maintain the integrity and reliability of the entire system.
