VALVE SEAT RING

Valve seat rings are integral part of valve train assembly consisting valve spring, spring retainer, cotter, guides and valves, fitted on cylinder block head to seal combustion chamber with face of inlet and exhaust valves. Its round shaped angle helps engine valves to rest on its surface and transfer heat to cylinder blocks. Widely, seat rings are made from magnetic and nonmagnetic materials, like PL12MV, WELL-TITE, MAR-TITE & high chrome/nickel content with centrifugal process for high-end heavy-duty engines.

During refurbishment or overhauling of engine, orientation of seat rings with valves and guides must be aligned, otherwise it will result in to bending, crack, quick wearing of parts and loose fitting of seats often end up falling out result in failure and damages engine.

Seat rings comes in variety of shapes and sizes, which SSV manufacture understanding its application and uses considering its thermal stress, frictional load and impact stress for durability. Oversize seats with high seat width are manufactured to meet demands of aftermarket industry, which should be concentric for tight seal and proper cooling of engine. We also do overlay of special cobalt-based material on angle of seat rings to withstand high temperature and protect from corrosive gasses. Our wide material range gives customer flexibility to choose from, for its use customise it as per design and dimensions.
