The SIMMEL Valve limit switch 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 the valve as a switch signal, which is received by the remote 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.
