Valve Seat

Valve Seat Inserts are made of Chrome alloy steel to withstand extremely high temperature in combustion chamber of four stroke engines, using natural gas, L.P. gas, lead free fuels etc. These are suitable for use in light alloy aluminum and cast iron cylinder heads. Due to the high alloy contents and excellent heat resistance properties, Valve Seats Inserts are able to dispose the heat quickly surrounding the engine valves. As during the running of all four stroke engines, the engine valve contacts the valve seat inserts for a very short moment, it is only when the head of the engine valve has a chance to transfer the heat to the valve seat, which ultimately transfer it to the water jacket of the cylinder head. This is why our Valve Seats Inserts cools faster, assures longer engine valve & valve guide life, which finally extends the engine life. Also the hardness & the granule structure of the our Valve Seats Inserts is such that it can be cut & machined easily with existing tooling and will not clog the cutting stones and cutters. We have complete in-house capabilities for development, metallurgy, casting, tooling and testing. The casting, which is the most important and typical factor in the manufacturing of the Valve Seat Inserts, is done on latest high frequency induction melting furnace. These are individually and centrifugally casted, as the case may be, under the strict supervision of qualified metallurgists.
