I am looking for some information from refiners who have installed proximity switches on their switch valves and drum isolation valves. Our Delayed Coker currently has a manually operated Wilson Snyder switch valve and manually operated wedge plug valves for drum isolation.
We would like to install a safety system to minimize the potential of swinging into a blocked in valve without automating our switch valve and wedge plug valves at this time.
How does one go about setting up these proximity switches? What type of switch is typically used?
Thanks in advance.
