Cat engine valves are manufactured to withstand high temperature and pressure in the engine cylinders. Cat engine valves are assembled in the cylinder head. Cat engine valves are designed to draw air in and out of the cylinders. The air drawn helps to ignite the fuel which helps to drive the pistons up and down.
