Pneumatic valve actuator
Limit Switch Box
A limit switch box provides a visual and electrical remote position feedback on automated valves.
It allows various built-in switches and can be used under high temperature, low temperature and other harsh environments.
It is also used as an important valve interlock protection and remote alarm indication in an automatic control system.
A limit switch box is used to output the open or closed position of the valve as a switch signal.
The signal is received by the programmer or sampled by the computer.
After confirming, the next step is executed.
