The positioners guarantee that the valve position (controlled variable x) is always assigned to the input signal (reference variable w) before any action is taken. They do so by comparing the input signal, which comes from a control system, with the control valve's travel and issuing a corresponding output signal pressure pst (output variable y).

In the case of double-acting actuators, a reversing amplifier is used to generate two opposing signal pressures.

Features:

The product has versatile mounting options, making it suitable for both normal and split-range operation. Its dynamic response is exceptional, and it is not influenced by the supply air. Additionally, it has an adjustable proportional band and air output capacity, low air supply consumption, and a compact design that is insensitive to mechanical vibrations. Maintenance is also low.

In hazardous areas, there are versions available for use with intrinsic safety type of protection such as II 2G Ex ia IIC T6 or II 3G Ex nA II T6 for Zone 2.

The product also has flameproof enclosure type of protection with Type 3766 Positioner and Type 6116 i/p Converter as shown in Figure 2. Another option is direct attachment to Type 3277 Actuator as illustrated in Figure 3.

If using IEC 60534-6, the product can be attached to a variety of actuators. Alternatively, when using rotary actuators, it can be attached according to VDI/VDE 3845.

Applications:

Positioners are used in conjunction with control valves to ensure precise control over the flow of fluids or gases. These devices can be either single-acting or double-acting, depending on the specific application requirements.

Single-acting positioners use one pneumatic signal in order to adjust the valve's position. This signal is typically used to move the valve stem in one direction, with the spring returning it to its original position. Single-acting positioners are commonly used in simple control applications where accuracy is not critical.

Double-acting positioners, on the other hand, use two pneumatic signals to control the valve's position. These signals work in opposition to each other and can be adjusted to achieve precise positioning of the valve. Double-acting positioners are typically used where precise control is necessary, such as in industrial or process applications.

No matter which type of positioner is used, they are always attached directly to the control valve. This allows for easy integration into existing systems and ensures that the valve is operating at peak efficiency.
