Engine Valves

Engine Valves
  • Inlet valves and outlet valves seal off the combustion chamber and control the charge exchange process in the engines. Valves are mechanically, highly strained components which are additionally subject to corrosive influences.
  • The outlet valve is additionally heated by the passing hot exhaust gases during outlet clock opening. The valves are cooled down mainly by conducting heat via the valve seat insert to the cylinder head.
  • The smaller proportion of the heat is conducted via the valve guide to the cylinder head. Inlet valves reach temperatures of approx. 300 °C to 550 °C, outlet valves can get up to 1,000 °C.
  • The Engine Valves are made up of heat resistant alloy.
  • Various processes like Chrome flash on Stem Satellite on seat and tip area, Nitriding / Tuft riding are offered.
  • The machining of outer diameter and radius of engine valves are processed on CNC Machine.
