Marine Diesel Exhaust Valve

Compact, zero-leakage exhaust valve with cooling and silent actuation for submarine applications.

 

Marine Diesel Exhaust Valve

The Diesel Exhaust Valve is designed for safe, silent operation in submarine exhaust systems. Its zero-leakage sealing prevents seawater ingress, protecting the engine from flooding during shutdown or standby. An integrated cooling system reduces exhaust gas temperature, while a seal protection mechanism prevents fouling buildup and extends operational life. The valve is engineered for compact spaces with a customisable layout and features a fast, low-noise actuation design to meet naval acoustic requirements. Suitable for harsh marine environments, it operates up to 500°C and 40 bar, and is available in corrosion-resistant stainless and nickel alloys.
