Definition - What does Petcock mean?
Petcock is a small valve that is used to control the flow of gas and liquids in engines. The working of the device remains the same as a boiler hence it is used to drain off the unwanted materials from internal combustion engines. Depending on the requirements, it can be installed in the fuel system or in the radiator. The valves have different designs though they all work on the same principle.
