Conventional fuel Valve

Mini-sac Valve

Slide-type fuel Valve

Slide fuel-valves come as standard on all new MAN B&W engines but can also be retrofitted on MC engines.
The slide fuel-valve eliminates the so-called ‘sac volume’, which reduces fuel-oil consumption and, furthermore, eliminates dripping from the fuel-valve nozzle.
Compared to conventional valves, the slide fuel-valve has NOx-reduction potential.
The reduced sac volume leads, by nature, to an improved combustion process, resulting in fewer deposits throughout the gas ways and a reduction in overall emissions, such as HC, NOx and particulate matter.

The slide type fuel valve has the below advantages compared with conventional fuel valve so it’s applied to all engine type for standard one.
