The flange K 67004 is a precision structural connection component designed to join air branches K 67002 and K 67003 within the Sulzer ZV40/48 air charging system. Its primary function is to provide a secure, accurately aligned, and pressure-tight connection that ensures uninterrupted airflow between the interconnected intake components. Manufactured from high-strength, corrosion-resistant materials, the flange is engineered to withstand vibration, pressure fluctuations, thermal expansion, and continuous mechanical loading encountered in demanding marine and industrial diesel engine applications. Precision-machined contact surfaces guarantee reliable sealing and simplified assembly procedures, while maintaining dimensional stability over long service intervals. By preserving the integrity of the air charging system and minimizing leakage losses, the K 67004 flange contributes to efficient turbocharging, stable combustion conditions, improved engine performance, and long-term operational reliability.
