The most common boiler valve problems occur when valves are not maintained and inspected regularly and correctly; valves get damaged or broken most often due to corrosion, wear, and contamination. Regular maintenance helps prevent this.
Furthermore, the lifespan and functionality of a boiler valve is affected by the quality of maintenance and repairs, as well as the overall quality of the valve itself. Without quali ed, effective maintenance and/or repair, and with the stress of the three aforementioned factors, the following specific problems can happen to valves:
6) Failure, especially if motorized
Now let’s take a further look at what leads to these problems.
For these purposes, maintenance can be de ned as cleaning, replacing, remachining, general repair, and inspection. When this is not done correctly or often enough, the valve’s relieving capacity can be affected. Operationally,...
As problematic as these issues can be—along with how catastrophic they can be—there are simple steps that can be taken to avoid them, ensuring you get the most out of these critical boiler parts.
These steps are twofold:
1) Buy High Quality Valves
This can seem self explanatory, but many people often choose to buy the least expensive valves, or simply don’t know how to differentiate between a good and a bad one. In the case of the former, it cannot be overstated that purchasing a valve simply based on the lowest price can become a major problem.
Boilers are a very substantial investment, and when choosing the right valves, a poor quality product can ruin an otherwise good and expensive piece of machinery. When you compare the relative cost of a high quality valve to the cost of valve and boiler failure,...
