Engine Intake & Exhaust Valve

Engine valves are one of the engine’s most critical components. They must withstand extreme temperatures, pressures, hitting impacts and loads during its lifetime. Because the operating temperatures of the intake and exhaust valves are highly different, different materials, structures, and manufacturing methods are required and implemented for each type of valve. CTP Manufacturing of valves includes various processes, such as forging, machining, welding, nitriding, and specialty coatings, that provide strength and durability.
