VF04E Limit Switch
The VF04E Limit Switch is a field instrument used to detect valve status in automatic control systems. It outputs the open or closed position of a valve as a switching (contact) signal, which is received by a programmable controller or polled by a computer for sampling. Once confirmed, the next program step is executed. The product can also serve as interlock protection for critical valves and as a remote alarm indication in the system.
