The valve H 27702 is a critical flow-control component within the Sulzer ASL25 engine’s combustion system, responsible for regulating the intake and exhaust gas exchange during each engine cycle. Engineered for high-temperature resistance, wear durability, and dimensional stability, this valve ensures tight sealing, efficient airflow, and optimal combustion performance. Its robust construction and precision machining reduce leakage, support consistent power output, and extend service life under continuous heavy-duty operation in marine and industrial environments.
