For a long time, the cure for diabetes type 1 and type 2 has relied on agonizing insulin shots for patients or insulin infusion via mechanical pumps. Regarding this, experts have been creating artificial pancreatic beta cells with the he…
A valve positioner is a device that adjusts the valve actuator's position based on a control signal.
Valve positioners compare a control signal to a valve actuator's position and move the actuator accordingly. They are used with both linear valves and rotary valves. Valve positioners are used when the 0.2 to 1 bar pressure in the diaphragm chamber is not able to cope with friction and high differential pressures.
The positioner is fitted to the yoke of the actuator and is linked to the spindle of the actuator by a feedback arm in order to monitor valve position. When a control signal differs from the valve actuator's position, the valve positioner sends the necessary power to move the actuator until the correct position is reached. This uses a high air supply.
Positioners should be installed if the valve is intended for use in a control application.
Scope of the Report:
This report focuses on the Valve Positioners in global market, especially in North America, Europe and Asia-Pacific, South America, Middle East and Africa. This report categorizes the market based on manufacturers, regions, type and application.
Many oil & gas, petrochemical and process engineering plants are now operating with wide ranges of temperatures, pressures and flow rates. Harsh environments require valve and control products to function in severe service applications, requiring tougher and more reliable components with the ability to withstand extreme temperature or pressure fluctuations and maintain chemical and corrosion resistance.
Plant operators now look to control and monitoring solutions that can cross multiple applications. For valve positioner technology, developments in construction materials have needed to keep pace with these changing application requirements.
The valve position and control market is largely driven by changes in customer requirements, which then impact system design, enclosure construction or performance capability. In hazardous zones, for example, stainless steel has replaced aluminum in the construction of valve positioner enclosuresan innovation driven by customer requirements in the oil and gas industry.
The worldwide market for Valve Positioners is expected to grow at a CAGR of roughly 3.9% over the next five years, will reach 1460 million US$ in 2023, from 1160 million US$ in 2017, according to a new GIR (Global Info Research) study.
