What Is a Fuel Check Valve?
A fuel check valve, also known as a non-return valve, is a component used in fuel supply systems to control the flow of fuel.
It prevents backflow, playing a crucial role in maintaining the proper functioning of an engine by preventing fuel leakage and reverse flow.
Commonly used in conjunction with various fuel tanks and fuel pumps, fuel check valves are known for their reliability.
In automotive applications, they ensure a unidirectional flow, especially important when fuel vapors from the fuel tank flow into the canister.
Typically, a fuel check valve consists of a spring and a ball or a rod-like valve body, a design that facilitates its function.
