Electric valve operation
Thread Content
For electric valves that are not connected to the DCS, if the valve is quite tall and difficult to operate, is the switching control of the valve usually handled via the panel on the electric actuator (with a separate operation platform), or are wires run from inside the electric actuator to an operation column for control? If it leads to the operation column, this wiring design can generally be handled by the manufacturer of the electric valve, right?
The control column is too expensive. Work with the operation platform. It’s cheaper. Ensure the operation platform is securely fixed, and proper safety measures are in place.
We had a useful external control station (CSE) in our previous projects; was that external control station expensive? Do any manufacturers know about it?
I’m not very familiar with this area yet; based on the answers above, the control columns are too expensive. Work with the operation platform. It’s cheaper. Ensure the operation platform is securely fixed, and proper safety measures are in place. I also learned * it
However, it is also necessary to consider the actual layout to see if there is any space where an operation platform can be installed.
For safety reasons, the emergency shut-off valve can be connected to a ground-level control panel
Emergency cut-off valves are usually connected to the DCS, right?
DCS is certainly available, as are on-site operation panels
