Valve Seat Inserts
These are super alloyed cylindrical parts with high resistance to heat, and wear & tear. Mechanical properties and strength of the inserts are very high and are usually made in two types: inlet & exhaust. These fit into the cylinder head's parent bore, while the valve is fitted into the seat inserts. The seat angle is the most critical parameter of the valve seat insert and is manufactured with high precision machines and toolings.
Designed to suit a wide range of applications, Cooper Corporation's valve seat inserts are manufactured with the necessary tolerance and high-quality levels to allow installation directly into the cylinder head guide bore without any additional work.
All valve seat inserts are centrifugally cast on Casting Machines. The centrifugal process assures that the castings are sound and will pass the radiographic examination.
