Product description:
Guardbox Limit switch boxes are electromechanical devices ideal for monitoring the remote operation of industrial valves in plants,
designed and manufactured for demanding applications in extreme environments and where there are requested high standards for safety
and reliability products. The Guardbox devices are used to control the position of the valve and provide high accuracy electrical feedback
signal of valve status to plant control systems. Guardbox devices are equipped in standard configuration with a 3D high visibility position
indicator that represent a true indication of valve position. The indicator is visible on all 4 sides and is fully adjustable on 360° without
disassembly. Guardbox limit switch boxes are built to be installed on valves or actuators which drive the process valves from closed to
open position (Normal acting) or from open to closed position (Reverse acting) .
Normal acting
is considered full CW when the process
valve is closed and CCW when the process valve is open.
Reverse acting
is full CW when the process valve is open and CCW when the
process valve is closed.
