What is a Control Valve Positioner?
In industrial processes, control valves play a crucial role in regulating fluid flow, pressure, and temperature. However, to achieve precise control, a control valve positioner is often necessary. A positioner is a device that accurately controls the movement of a control valve, ensuring it reaches the desired position in response to a control signal.
Working Principle of Control Valve Positioners
The working principle of a control valve positioner is based on a feedback control loop. The positioner receives a control signal from a controller or PLC, which compares the desired valve position with the actual position. If there's a deviation, the positioner adjusts the valve's movement to match the desired position. This process occurs continuously, ensuring the valve remains at the correct position.
Types of Control Valve Positioners
There are two primary types of control valve positioners:
1. Pneumatic Positioners: Use compressed air to move the valve stem.
2. Electric Positioners: Use an electric motor to move the valve stem.
How Positioners Improve Valve Performance
Control valve positioners enhance valve performance in several ways:
1. Accurate Control: Positioners ensure the valve reaches the desired position, reducing errors and improving process control.
2. Increased Precision: Positioners can achieve precision of ±1% or better, depending on the application.
3. Faster Response Times: Positioners respond quickly to changes in the control signal, reducing process upsets.
Benefits of Using Control Valve Positioners
The benefits of using control valve positioners include:
1. Improved Process Control: Accurate control of valve movement ensures consistent process conditions.
2. Increased Efficiency: Reduced errors and faster response times lead to improved process efficiency.
3. Extended Valve Life: Positioners reduce wear and tear on valves, extending their lifespan

    If you use 4-20mA as a control signal, then two gauges are enough. The third gauge would have been used on older 3-15 psi control signal positioners (but can still be is used with 4-20mA control signal when you have double acting actuators)
