The new Yanmar Eco Diesel range of low-NOx and fuel-efficient high-performance marine engines includes a custom-designed self-actuating temperature control valve for the water cooling system.
The new Yanmar Eco Diesel range of low-NOx and fuel-efficient high-performance marine engines has been developed with an Amot custom-designed self-actuating temperature control valve for the water cooling system.
For the project, Yanmar required a design that enabled the production of more compact engine where the thermostatic valve was installed "within the envelope" of the engine instead of outside it, as would normally be the case.
Using proven Amot thermostatic valve technology which requires no external power source, Amot developed a customised valve housing which allowed for maximum flow and minimum pressure drop.
The low friction characteristics plus vibration and shock resistance also ensure a long and reliable service life.
Designed to combine smooth running performance with durability, Yanmar marine diesels are produced for use as generator engines on large ships or propulsion units in both repowering and new boat applications.
