This is a fuel switch valve, primarily used to control the opening and closing of the fuel supply. It is commonly found in equipment with small engines, such as motorcycles, lawnmowers, etc. The valve is made of metal, providing good corrosion resistance and durability, capable of stable operation under various conditions, ensuring reliable operation of the fuel system. It has clear \"ON\" (open) and \"OFF\" (closed) markings. During operation, the state can be switched by turning the handle marked \"FUEL\", which is simple and intuitive, facilitating quick use for the user. The interface is finely machined, allowing for a tight connection to the fuel circuit, effectively preventing fuel leakage and improving user safety. The overall structure is compact and small, not taking up too much space during installation, adapting to the fuel system layout of various small equipment, offering convenient use of equipment space.
