Engine Valve Materials:
1, Engine valves are one of the components in internal combustion engines that are highly stressed. The need for reliable engine operation dictates that engine valves be capable of exhibiting resistance to repeated and continuous exposure to high temperature, high pressure from the combustion chamber, and mechanical loads and stresses from the engine dynamics.
2, The intake valves on internal combustion engines are subjected to less thermal stress because of the cooling effects of the incoming air/fuel mixture that passes by the valve during the intake cycle. Exhaust valves, by contrast, are exposed to higher levels of thermal stress by being in the pathway of the exhaust gases during the exhaust cycle of the engine. In addition, the fact that the exhaust valve is open during the exhaust cycle and not in contact with the cylinder head means the smaller thermal mass of the combustion face and valve head has a greater potential for a rapid temperature change.
3, Intake valves, because of their lower operating temperatures, are typically made of materials such as chrome, nickel, or tungsten steel. The higher temperature exhaust valves may use more heat-resistant metals such as nichrome, silicon‑chromium, or cobalt-chromium alloys.
Valve faces that are exposed to higher temperatures are sometimes made more durable by the welding of Stellite, which is an alloy of cobalt and chromium, to the valve face.
4, Other types of material used for the fabriafter market dieselion of engine valves include stainless steel, titanium, and Tribaloy® alloys.
In addition, coatings and surface finishes can be applied to improve the mechanical properties and wear characteristics of the engine valves. Examples of this include chromium plating, phosphate plating, nitride coating, and swirl finishing.
Isuzu 4JA1/4JB1 8-94133-275-1/0 8-94247-875-1 engine valve photos:
1- Raw materials:
We only use highest quality primary 21-4N,4CR9SI2 and 40CR.
2- Complete Tests:
The cylinder heads unitary pass by leak test of valves, for water circuit pressure test and oil circuit pressure test.
Checks controls on the machining are made across different steps of the manufacturing process and the results are automatically compared to the specifiafter market dieselions registered in our systems.
Finally, in a unified way, a visual check of the entire piece before packaging is made.
3- ID System:
We have implemented a system of identifiafter market dieselion and trace-ability of our products, which makes possible to correctly identify and separate each and every one of our engine valve.
We also supply Mitsubishi, Toyota, Nissan,Komatsu,Hino,Cummins, , Hyundai,Deutz,heavy duty truck engine cylinder head with high quality and fast delivery time.
