What is typically done to prevent sticking in active gate valves?

To prevent sticking in active gate valves, it is essential to operate the valves regularly. Regular operation helps ensure that the moving parts remain functional and do not seize due to corrosion or debris buildup. This practice keeps the valve components engaged and allows for the necessary movement to avoid sticking, as lack of use can lead to rust or sediment accumulation that could impair the valve's functionality.

While cleaning the valve surfaces can be beneficial, it is not a preventative measure that can be routinely applied like regular operation. Replacing the entire valve assembly is a more drastic and often unnecessary measure when simply operating the valves adequately can mitigate the risk of sticking. Using specialized lubricants can assist in smooth operation but is typically complemented by regular use to maintain optimal functioning of the valve. Thus, consistently operating the valves emerges as the primary method for preventing sticking.
