Клапан сброса масла, Oil relief valve Perkins #4138A057

The oil pressure relief valve 4138A057 helps to ensure the right amount of oil is available at every phase of engine operation. When the engine is cold, more oil is allowed to flow to protect the bearings as oil is cold and thick. As the engine heats up, the oil becomes thinner, and the valve reduces the flow. Preventing too much oil flooding the engine parts and spraying onto the cylinder walls, resulting in excessive oil consumption and a reduction in overall engine power. Oil relief valves are selected to ensure your Perkins engine consumes the least oil and operates effectively.
