The housing with code number K 27402 serves as the structural body of the starting valve in the ZV40/48 diesel engine. It encases the spindle and related internal components, providing robust protection and alignment. Built from corrosion- and pressure-resistant materials, this housing ensures the valve operates safely and efficiently under high-pressure air injection. Its design supports quick servicing and dependable engine starts even in harsh marine environments.
The spindle coded K 27401 is a key moving component of the starting valve in the ZV40/48 diesel engine. It functions as the actuator that enables or blocks compressed air flow to the cylinders during engine start-up. Engineered for high precision and durability, the spindle must operate flawlessly under sudden pressure changes and high thermal conditions. Its role is essential for reliable engine ignition and smooth transition to full operation.
The cover with splash tube, code 11.01213-0057-1.0, is an integrated component designed to direct lubricating oil inside the MAN L21/31 engine. It prevents uncontrolled splashing, reduces oil loss, and ensures targeted lubrication of internal parts such as bearings and gears. This component plays a crucial role in maintaining oil cleanliness, reducing wear, and supporting smooth engine operation in demanding conditions at sea or in power plants.
Round steel bars coded EN43AE01100028 are essential raw materials used in the manufacturing and repair of MAN L21/31 engine components. These bars are made from high-grade steel with excellent machinability and strength, enabling them to be transformed into precision-engineered parts such as shafts, pins, or custom fittings. Their consistent diameter and metallurgical properties ensure that the resulting components meet the rigorous demands of marine and industrial engine performance.
The disc with code 11.01299-0138.0 is a key mechanical element in the MAN L21/31 engine, typically used in rotational or sealing assemblies. Its precise machining and material strength allow it to maintain alignment, absorb stress, or serve as a spacer or retainer depending on its location within the engine. This seemingly simple part contributes to overall engine balance, durability, and vibration control, particularly in high-speed and high-pressure operational environments.
The lower spring plate, identified by code K 27502, is an essential support element for the inlet valve spring assembly in the ZV40/48 engine. It provides a stable base that maintains the correct spring tension, ensuring consistent valve timing and proper seating. This component must endure repeated cycles of compression and rebound, and it is built from durable materials to resist fatigue. Its role is crucial in ensuring that the inlet valve operates efficiently, helping the engine achieve optimal air intake and combustion performance.
