New Valve Spindles for MAN B&W Two-Stroke Engines

Posted on May 20, 2005

MAN B&W Diesel has developed a new exhaust valve spindle that will increase by more than 50% the Time Between Overhaul (TBO) of its entire two-stroke engine range.

Taking 10 years research and development, the new engine component, DuraSpindle, is based on a durable alloy hard facing that is toughened through a patented welding, rolling and heating process to prevent critical indentation marks causing 'blow-by' and occasional cracking on valve spindle seats as a result of the combustion process.
