Product Description:
The positioners have the important task of ensuring that the valve is positioned based on the desired input signal from the control system. This involves assigning the controlled variable, which is the valve position, to the reference variable, which is the input signal. The positioners accomplish this task by comparing the input signal to the travel of the control valve, and providing an output signal pressure, referred to as pst.
Furthermore, the positioners are also responsible for producing two opposing signal pressures through the use of a reversing amplifier for double-acting actuators. This allows for precise control over the positioning of the valve, ensuring that it functions as intended.
Overall, the role of positioners is essential in maintaining proper control over the valve, and it is important to carefully consider the design and implementation of these components in any system utilizing control valves.

Applications:
Positioners can be attached to pneumatic control valves for increased functionality. These devices provide accurate control of valve stem position and can be either single-acting or double-acting.
Single-acting positioners use air pressure to move the valve stem in one direction, while using a return spring to move it in the opposite direction. They are suitable for simple applications where precise control is not critical.
On the other hand, double-acting positioners use air pressure to move the valve stem in both directions, providing more precise and reliable control. They are commonly used in applications where accuracy and control are essential.
By attaching positioners to pneumatic control valves, operators can achieve greater control over processes and ensure that valves operate according to specific parameters. This can result in increased efficiency, reduced costs, and improved safety.
