How to Fix a Burnt Valve
A valve is a control mechanism that allows one to restrict or allow fluid flow (liquid, gas, etc.). When a valve fails or becomes damaged due to various reasons, replacing it with a new valve needs to be done to restore its functionality. A burned valve is an example of such a situation when replacement of this component will be necessary. These valves usually carry high pressure and temperature because they are connected to where a high amount of energy transfer occurs. If any leakage occurs from these valves, it may lead to serious damage; hence, their maintenance and proper functioning are important. Today I am going to discuss how to fix a burnt valve.
How Valves Get Burnt?
Poppet valves and gate valves can both get damaged. Poppet valves use a ball to restrict the flow of fluid, while gate valves use a flap (or disc). Both types of valves can get burnt if they’re not handled properly, or if too much force is used when opening or closing them.
Faults Due to Mechanical Problems
Popped-off poppet ball or disk (flapper) will result in a burnt valve as they have a tendency to get stuck inside the seat hole of these valves and obstruct their working. In the case of gate valves, when a fluid pressure given is much higher than its design value, then the flap carrying this pressure will pop up from the seat and move with it upwards, resulting in damage. The same happens in poppet-type valves, wherein the flow of fluid causes that component to jump out from its original position.
There is a chance that the valves will burn themselves if they are exposed to extreme temperatures. If there is something blocking the valve, it may also cause the valve to stop working.
Faults Due to Flow Problems
Valves can fail when there is too much pressure on one side, due to factors like an open-ended piping system or flow reversal. Fluid flowing in the opposite direction of what it is supposed to do can cause serious wear and tear of these valves.
Step-wise Guide on How to Fix a Burnt Valve
If your gas stove’s burners keep shutting off or the flames go out, it could mean there’s something wrong with the burners or the valves that control them. To fix a burnt valve, first turn off the gas and then unscrew the valve. Next, use a wire brush to clean the valve’s seat. Finally, screw the valve back on and turn the gas back on.
If your electricity is not working, the first step is to disconnect your electricity supply. This will prevent you from getting hurt while you are repairing the problem. Next, use a wrench or screwdriver to see if you can unscrew the top part of your burner. It is important to wear gloves while you are doing this so that you do not get shocked.
This step is only necessary if you are planning to replace the whole unit entirely. Therefore, if there are signs of cracks on any part of the valve, it would help if you can buy new ones instead of completely fixing these flaws since this could save you more money and time in the long run.
If your pilot light goes out, it might be because of a broken wire. You can replace the pilot light at your local hardware store. If your gas valve is defective, you might need to replace some parts. You can find these parts at your local hardware store.
If you have damaged valves and nothing else is working to fix them, you can call in professionals to help. This will cost more than doing it yourself, but it will be done more quickly.

Precaution While FIxing a Burnt Valve
- To fix a burnt valve, never use a pointed sharp instrument as that may do more damage to the inside of your engine cylinder head and making it much harder for you to remove the burnt valve from its place.
- Always wear protective glasses while working on fixing a burned valve so that any small debris or particle does not hit your eyes directly. This is very important because if such a thing happens, it might lead to permanent blindness or loss in vision quality which is really serious and can be avoided with simple precautions like wearing safety glasses while working on fixing valves.
- Always wear a face mask or hand gloves to avoid getting burnt by hot ash produced during the cleaning up the burnt particles from the engine cylinder head where we want to replace the burnt valve.
- Always have a fire extinguisher at hand in case of any emergency so that you can put off the fire immediately before it spreads to other parts of the engine and causing more harm than good.
- Never try to fix a burnt valve if you do not know what you are doing, as there is a risk of endangering your life in such cases by making things much worse instead of solving them.
Burn valves are a widespread problem in gas stoves as they will be present in every corner of the house to cook your meals and keep you warm on cold days. Therefore, it is of utmost importance that we know how to fix these problems, especially if our lives or properties are at stake. Hopefully, this article would help you out with how to fix a burnt valve which you need immediately before doing something else important like cooking for your family.
