Positioners: The Invisible Heroes of Mechanical Installations

In mechanical installation projects, many auxiliary components are used to ensure that work is carried out properly and efficiently. One of the most important of these is the positioner. In this article, we will discuss what positioners do, their types, their benefits, and the points to consider when purchasing them. We will also emphasize that Astel Mekanik Tesisat is one of the reliable suppliers offering a wide range of high-quality positioners.

What Is a Positioner?

A positioner is used to move the valve stem to the correct position by increasing or decreasing it according to the setpoint coming from the control system. The positioner is mounted on the actuator yoke and connected to the actuator stem with a feedback arm in order to monitor valve position.

Types of Positioners

Positioners can generally be classified as:

• Pneumatic

• Electronic

• Electro-pneumatic

• Digital

What Is Positioner Adjustment?

Positioners adjust the position of the valve plug stem according to the electrical or pneumatic input signal received from the controller. The positioner compares the signal coming from the control device with the movement and position of the valve stem, and sends a pneumatic output signal (Pst) to the actuator according to the required set value.

Benefits of Positioners

Increased efficiency:Positioners help the valve reach the correct position accurately, reducing response time and improving process efficiency.

Improved control quality:Valves held at the correct position provide more stable control, less deviation, and better process results.

Better operating comfort:They support smoother and more stable operation in automated systems.

Improved safety:By ensuring the valve reaches the correct position, positioners help reduce control errors and improve system safety.

Points to Consider When Buying a Positioner

There are several important factors to consider when purchasing a positioner:

Load and actuator compatibility:The positioner must be suitable for the actuator and valve characteristics of the system.

Material quality:The materials used in the positioner should be durable and long-lasting.

Adjustability:A positioner with flexible adjustment capability provides more versatile use in different applications.

Ease of use:A user-friendly design makes commissioning and operation easier.

Price-performance balance:A good balance between quality and price helps ensure a long-lasting investment.
