A control valve positioner is a device used to increase or decrease the air load pressure driving the actuator of a control valve until the valve’s stem reaches a position that is precisely …

Positioners essentially act as control systems within themselves: the valve’s stem position is the process variable (PV), the command signal to the positioner is the setpoint (SP), and the …

Nov 5, 2025 · A valve positioner is a critical device used in automated control systems to ensure a valve’s actuator is in the exact position required by the process controller.

Jan 16, 2019 · Valve positioners are devices used to put a valve in correct position by sensing the valve’s location and communicating to the actuator to move it.

Valve positioners make sure the valve opens to the right spot each time. You see this in oil and gas, chemical plants, power stations, and water treatment plants.

What is a Valve Positioner? As a common control valve accessory, the valve positioner delivers pressurized air to the valve actuator so that the position of the valve stem or shaft corresponds …

Mar 7, 2025 · Valve positioners are essential components in modern industrial process control systems, ensuring precise and reliable valve operation. From their fundamental principles to …

A positioner for a control valve is used to adjust a valve’s position based on a desired set point for a process variable, whether it be pressure, temperature, or flow.

A valve positioner is a precision control device installed on a control valve actuator to ensure the valve opens to the exact position required by the control signal from the controller (such as a …

A valve positioner is a device that adjusts the valve actuator’s position based on a control signal. These positioners are best used in control applications because of their precision.
