We can accept customized valves: such as OEM valves to meet the needs of customers。The valve is an important component in the internal combustion engine, used to control the entry and exit of gas in the cylinder. In a four-stroke engine, the valves are divided into intake valves and exhaust valves, which are opened and closed to control the entry and exit of air and fuel to achieve combustion and exhaust gases. The opening and closing of the valves is controlled by the camshaft or valve mechanism and is a key component for the normal operation of the engine.
