The changeover valve regulates the supply of gas to your appliances. LPG is a high-pressure gas and needs to be restricted down to 37mb pressure.
Most LPG appliances work on 37mb for propane and 30mb for butane.
If the gas supply was not restricted you would not be able to control the flame of theappliance.
There are many types of changeover valves to choose from. Some very cheap, some very expensive, but you only get what you pay for.
The more expensive valves come with an opso built in. Basically, this stops too much gas entering the supply.
They will normally have a reset button located at the back of the valve should it activate.
The changeover valve comes in different models, manual or auto.
Basically, this means with the manual valve you have to change over the gas from one bottle to another.
The auto version does this automatically. Most also have a small window that tells you what bottle supplies the gas.
When it comes to gas be it natural or LPG, always ensure you use a gas safe registered engineer to work on your gas supply and appliances.
Gas is very dangerous in the wrong hands. Just because someone tells you they can carry out any work you require for a much cheaper rate than a Profesional could cost a life.
We can supply and install a new LPG changeover valve for you if you live in Suffolk or Essex.
