Valve limit switch box is a field instrument used in automatic control systems to detect the status of valves. It is used to output the opening or closing position of valves as a switch signal, which is received by the program controller or sampled by the computer. After confirmation, the next step of the program is executed. This product can also be used as an important valve interlock protection and remote alarm indication in automatic control systems. The appearance design is novel and beautiful, with a three-dimensional position indicator that can clearly identify and display the position of the valve. The internal 8-contact internal circuit PCB board wiring is convenient to prevent short circuits. The control method can be selected according to the requirements of the on-site environment, including proximity switches, magnetic switches, and signal feedback devices.
