For marine and stationary engines<\/strong><\/p>\n

There is a high demand concerning operational reliability on combustion engines for stationary use and for ship propulsion. In addition, extended maintenance intervals introduce a huge advantage concerning operating costs.<\/p>\n

It was our target to optimize the above factors when the engines were overhauled and equipped with our seat rings.<\/p>\n

In combination with the material of the valves a suitable choice for the seat ring materials ensures that the wear at both the valve seat and seat ring will be reduced.<\/p>\n

The exhaust seat rings are mostly cooled. In general, to seal the ring, an O-Ring is used. Due to high temperatures this seal will become brittle and the sealing is not guaranteed. To improve this, a thin layer of tin as well as grooves are applied to the outer diameter of the seat rings, which requires high production tolerances.<\/p>\n

Examples of seat rings we have in our portfolio are MAK M20 and M25 as well as W\u00e4rtsil\u00e4 W20.<\/p>\n\n\n
