What is a Limit Switchbox

Limit switchboxes for valve monitoring are essential components in industrial and process control systems, designed to provide accurate and real-time feedback regarding the position of valves. These robust and reliable devices are typically attached to valve actuators and serve as an interface between the valve and the control system. Equipped with switches or sensors, they detect and transmit critical information such as valve open or closed positions, or any intermediate settings, to ensure precise control and monitoring of fluid flow.

Limit switch boxes play a pivotal role in enhancing safety, efficiency, and control within various industries, from oil and gas to manufacturing and water treatment, by providing valuable feedback on valve performance and facilitating quick responses to changes in process conditions or emergencies. They are integral to the automation and monitoring of valve operations, reducing the need for manual intervention, and optimizing overall system performance.

Westlock’s AccuTrak™ series are valve position monitors, commonly referred to as “limit switches,” provide both visual and discrete electrical position feedback of rotary and linear valves.

The AccuTrak™ family presents a comprehensive and seamlessly integrated solution for the monitoring of process valves. It unites switches and sensors, wiring terminals, enclosure, and local visual indication within a compact, all-in-one unit, purposefully designed for both weatherproof and hazardous location applications. This ingenious combination not only streamlines valve monitoring but also ensures a high level of functionality, all packaged in an rugged and space-saving design.
