Engine IN intake valve (EX exhaust valve 15261-13111) for Kubota D650, Kubota D750 and Kubota Z500 engine, with an overall length of 89.80 mm and a valve head diameter of 27.70 mm for Kubota tractors of the Kubota B5100, Kubota B5200, Kubota B7100 series with Kubota D650, Kubota D750, Kubota Z500 and other engines.

Engine valves are components located in the cylinder head (overhead valve engine) or engine block (lower valve engine). Their main function is to properly control the flow of air, the fuel-air mixture, and exhaust gases. There are two types of valves: intake valves, responsible for opening the chamber to draw in the appropriate amount of fuel mixture, and exhaust valves, responsible for removing gases generated during engine operation.

The valves consist of a rod with a disc at the end and are fully cast. Engine valves are made of special steel resistant to the extremely high temperatures generated during fuel combustion, known as heat-resistant steel.

Engine valves are components that wear out when working in difficult conditions and under the influence of high temperatures. The most common valve damage is valve stem abrasion and carbon deposits. Valve deposits are the result of using low-quality oil, and valve head wear causes leaks in the system and loss of engine power.
