Cylinder Heads &

Valve Stems:
DeServ lnternational's range of supply of valve stems covers almost all the engine models regardless of 2-stroke or 4-stroke. We believe quality of the components used in the engine plays a major role in increasing performance and extending time between overhauls. Since, the valve stems are used in the combustion area, which can lead to heavy corrosion, we recommend our clients to use Nimonic exhaust valves and also supply valve stems coated with thermal barrier coating to withstand corrosion in the combustion area.

Valve Seats:
DeServ International, supplies hardened face acidic-corrosion resistant seats of both cooled and un-cooled versions which are manufactured using innovative techniques to prevent coolant leak problems.

Valve Rotators:
DeServ International supplies valve rotators of Ball and Spring Rotation and also Turnomats manufactured by our Principal manufacturers in Europe which are precision crafted to exact tolerances using optimized designs and premium materials. Ball Spring Rotation valve rotator ensures that the temperature is equally distributed to the valve head to prevent localized stress and early wear of the valves. Turnomats are the most sophisticated & effective rotators which enhances the economic performance efficiency of the eng ines.

Apart from the above specified cylinder head spares, DeServ International supports in the supply of:

  • Valve Springs

Two-Stroke & Four-Stroke Engine Component Reconditioning Services

Our reconditioned engine components often exceed and outperform original manufacturer's standards.

Our expertise is guaranteed in a broad range of disciplines and materials, beginning with a detailed analysis that provides crucial information about how and why a component was damaged.

The operating life of a component is strongly affected by the operating conditions of the engine and its duty cycle. A detailed inspection prior to the reconditioning of engine components speaks volumes about the general health of an engine and provides early evidence of distress. Our specialized team focuses exclusively on engine components with expertise in reconditioning. Our Europe-based reconditioning unit has produced industry-leading advancements in welding techniques, featuring superior high-temperature corrosion performance that set the standard for marine component reconditioning.

Our offered European standard reconditioning process is a revolutionary development following years of careful research and development pertaining to the causes of component failure in Two-Stroke & Four-stroke engines.
