The valve positioners market is expected to grow from USD 1.8 billion in 2020 to USD 2.3 billion by 2027 it is expected to grow at a CAGR of 5.4% during 2021–2027. Valve positioners are devices that aid in the proper positioning of a valve by increasing or decreasing the air load pressure on the actuator. A typical valve positioner can detect the exact position of the valve and conveys this information to the actuator, which then moves the valve. These devices are located towards the end of the shaft or on the yolk or top casing of a pneumatic actuator. Pneumatic, electro-pneumatic, and digital valve positioners are the three types of valve positioners that are designed and manufactured. A valve positioner aids in improving valve action accuracy. The devices that are utilised to decrease or increase the air load pressure are known as valve positioners.valve positioners market aid in improving plant efficiency and lowering overall operating costs. Valve positioners offer advanced diagnostics without error or hysteresis, as well as control valve dependability and precise calibration. Not only that, but with the help of automatic collaboration functions, the smart valve positioners are simple to install and help to decrease setup time. Current control signals are converted to comparable pneumatic signals using an electro-pneumatic system that combines air and electricity. The pneumatic valve positioners supply precise air pressure to the valve actuator, allowing the valve to be moved to the desired position. Because of their anti-corrosion coating, these pneumatic valve positioners are ideal for industries like oil and gas, mining, and chemical. The digital value positioners have greater diagnostic capabilities and transform electrical signals to pressure signals thanks to the usage of microprocessors. Valve positioners are classified as single-acting or double-acting depending on how they are actuated.
