The conical clamping half-ring, marked with code number K 27529, is a key component in securing the exhaust valve assembly of the ZV40/48 diesel engine. Its conical geometry ensures uniform pressure distribution during valve installation and operation, reducing localized stress on the valve stem and associated parts. Designed to endure high thermal loads and constant vibration, this precision-engineered ring plays a vital role in maintaining valve alignment and sealing integrity, ultimately contributing to the engine’s reliable exhaust flow and long-term durability.
