DSS Valves and Safety in the Pulp and Paper Industry
“One of the most notable near misses happens when you close a valve, and it looks like it’s closed, but due to a blockage in the line, or a plugged or leaking valve seat, it does not close properly,” he said. “A lot of times when you’re working on this stuff you may not know until you take the last bolt out that there’s still pressure in a pipe that was supposed to be valved out.”
- The positive lockout feature in the DSS Valve means that to lock the valve out, it must be fully closed or fully open.
- A pin moves through a plate, ensuring it is completely open or closed.
- If the pin doesn’t go through the plate completely, the valve isn’t closed.
