some instances, you may need to overhaul the valve, which involves replacing all internal wear components. Check with your valve supplier for available seal kits you can use to make repairs.
Maintain the valve. Adjust your PM schedules or procedures once you gain a better understanding of how valve wear occurs in any given application. You can use tags to offer technicians quick, easy visual indicators of what individual valves do and how often they may need to be inspected.
WHEN TO REPLACE A VALVE Sometimes, a valve should not be repaired, but should instead be replaced with a new valve. Significant damage or other factors to critical components may require this. Some examples include:
Heavy corrosion may deteriorate the valve body, compromising its pressure-retaining capabilities and creating a safety risk
Major contamination that cannot be cleaned
Overtightening a valve at its end connections can cause damage, rendering it unusable for reinstallation
There are other factors that may require
replacement that have nothing to do with damage. You may determine that the cost
of a new valve, combined with the labour and testing involved in repairing an existing one, is more advantageous. Potential production downtime is important to consider in any maintenance activity. Reliable valve operation is critical to the
overall health and safety of your fluid systems. Being more familiar with the proper installation of valves, knowing how to troubleshoot valves, and being able to properly implement adequate PM plans for your valves can all contribute to safer, more efficient, and more profitable operation.
