What causes cracks in valves?
To know how to care for a valve, it is important to first understand why valves do crack. Therefore, as an alternative of increasing your chance of cracking a valve, it is possible for you to extend the service life of your valves and reduce cost with your tool budget. Below are common ways by which cracks occur in valves:
Valve crack by over-wrenching
This way of cracking is very much direct. The moment you curl too much, or apply more torque or force than is needed when you are installing the valve, it can be easily damaged. Irrespective of the weight of the valve, you can easily crack it by making use of a large wrench and strength by the application of too much torque on it.
Valve cracking by over-pressure
Every time valves are opened and closed, the gush of the media that passes through the pipe can result to an additional pressure in the pipe and valve. As a result of this, there could be a spike in force, or the hammer effect which can lead to the valve damage.
Valve cracking by great temperature changes
A great change in temperature can lead to an expansion or shrinkage of the valve and the pipe. The widely known example is freezing garden valve that is cracked during the winter period. Water tends to expand when it freezes. Therefore, great weather can effortlessly cause cracks in valves. Furthermore, extremely high temperature fluid such as saturated steam can lead to a great reduction in the pressure acceptance.
Valves cracking by using fittings, pipes, and other materials
The degree of strength, hardness, expansion rates, and electric magnetic properties of various materials vary- based on https://www.kp-lok.com/product/purge-valves/ their temperature. Making use of various material types of valves, fittings or pipes in your system can damage your valves when the temperature, magnetic field, or pressure changes.
It is imperative to take note of the various causes of cracks in valves. We have discussed some of the common mistakes that lead to cracks in valves. You should avoid them, and ensure that you have an understanding of how you can guard your valves, and lengthen their service life. Good Luck!
