Product Description:

The role of positioners in valve positioning is to guarantee a pre-determined assignment of the valve position (controlled variable x) to the input signal (reference variable w). Essentially, they act as an intermediary between the control valve and the control system. The positioners receive an input signal from the control system, which they compare to the travel of the control valve. To ensure accurate positioning, the positioner issues a corresponding output signal pressure pst (output variable y).

Additionally, a reversing amplifier is utilized for double-acting actuators which produces two opposed signal pressures. This ensures that the positioner can properly regulate the position of the valve in both directions of movement.

Applications:

Single-acting and double-acting positioners are designed to be attached to pneumatic control valves, aiding in their operation and control. These positioners are widely used in a variety of industrial applications, particularly in process control systems.

The single-acting positioners work in one direction, either to open or close the valve, while the double-acting positioners function in both directions. The positioners use pneumatic signals to adjust the position of the valve stem, thereby regulating the flow of gases or liquids through the valve.

The attachments of these positioners to the pneumatic control valves are relatively simple and straightforward. They can be easily installed and connected, and once in place, the positioners can be calibrated to ensure accurate and reliable performance.

Overall, single-acting and double-acting positioners play a crucial role in the smooth operation and control of pneumatic control valves in industrial settings. They enhance the accuracy, reliability, and efficiency of the valves, making them indispensable components of process control systems.
