Global Valve Positioner market is segmented on the basis of product type, application, and region. Valve positioners are basically used to upsurge or lessen the air control pressure that drives the actuator of the control valves until the valves stem reaches a position balanced to the output signal from the process variable instrument controller.

The positioners are mainly installed on the side-yoke or upper top casing of the pneumatic actuator for linear-sliding-stem control valves and at or near the end-of-shaft for rotary control valves. In either cases, the valve positioner is associated mechanically to the valve stem or valve shaft so that their position can be compared with the position dictated by the controller. Mechanical feedback then links back to the positioner to confirm that the process controller tells the positioner to modify position, also the feedback linkage addresses the positioner to confirm that a change in the valve position stem has occurred to give a sense of magnitude of the change in position. Positioners should be installed if the valve is intended for use in a control application.

Faster speed of response, pressure control across valves, split-ranging capabilities, and maintenance ability are the factors that lift growth of valve positioner market. Positioners are expected to calculate internally the correction for the detected stem position of valves, each of which has different full-open and full-close positions. Additionally, long-term reliability and sturdiness in several environmental cases ranging from cold to extremely hot (desert) climates are required.

The Valve Positioner market is classified, by type into Pneumatic Positioner, Electro-Pneumatic Positioner, Electric Valve Positioners, Digital or Smart Devices. Pneumatic positioners receive pneumatic signals (usually 3-15 psig). The positioner then supplies the valve actuator with the correct air pressure to move the valve to the required position. Pneumatic positioners are basically safe and can provide a large amount of force to close a valve.

Electric valve positioners normally receive electric signals and perform the similar functions as in the case of pneumatic positioners, but they use electricity instead of air pressure as an input signal. Single-phase, three-phase alternating current (AC) and direct current (DC) voltage are the three types of electric actuation in the global valve positioner market. Electro-pneumatic valve positioners transform current control signals to equivalent pneumatic signals and use a combination of air and electricity.
Digital or “smart” positioning devices use a microprocessor to position the valve actuator while monitoring and recording data. They function very similarly to an analog-type positioner, except the electronic signal conversion is digital rather than analog. Smart positioners are very accurate, use less air than analog positioners, and allow for online digital diagnostics.

The valve positioner market is classified, by application into Aerospace and Defense, Automobile, Marine, Oil & Gas, Mining, Water Treatment, Chemical and Petrochemical Industry, Thermal Power Generation, Solar Power Generation.

At oil and chemical plants, as well as steel, pulp, food, and pharmaceutical plants and other industrial facilities, valves are installed on pipes in order to control the flow rate of gases or liquids. Hundreds of valves are used at a small facility and thousands are necessary at a large facility. The valve positioner market is segmented, geographically into North America, Europe (Eastern Europe, Western Europe), Asia Pacific, Latin America, Middle East and Africa.
The key players in the valve positioner market are, Robert Bosch GmbH, Hilti Corporation, Stanley Black & Decker, Inc, Makita Corporation, Actuant Corporation, Techtronic Industries, Danaher Corporation, Hitachi Koki Ltd., SKF, Emerson Electric Co., Mindman, and Siemens.
