A Limit Switch Box, also known as a Valve Limit Switch Box or Valve Position Indicator, is a valve automation accessory used to indicate the open or closed position of an automated valve. Mounted directly on pneumatic or electric actuators, it provides both visual valve position indication and electrical feedback to PLC, DCS, or other control systems.
By providing accurate valve position monitoring, a limit switch box helps improve process visibility, reduce manual inspections, and support safe, reliable automation in industrial applications.
At Aira Euro Automation, we manufacture a complete range of limit switch boxes designed to meet different environmental conditions, protection requirements, and automation applications.
