<p>A valve control system includes general-purpose valves arranged in a pipe for flowing a fluid, first and second sensors, and a safety controller. The general-purpose valves are valves that can be opened and closed according to the electric signals, and are, e.g., solenoid valves, respectively. The first and second sensors are sensors that detect a state of flowing of the fluid from the corresponding valves, and are formed of, e.g., pressure switches, respectively. The safety controller is configured to satisfy the safety standards, and outputs signals for controlling the valves based on signals provided from the first and second sensors, respectively.</p> |
