1, A valve is a device to close and open a passage. Engine valves are devices that are used in internal combustion engines to allow or stop the flow of fluid or gas from cylinders or combustion chambers during the engine while the engine is operating.
2, These are also known as check valves which are used for air injection in vehicles as part of emission control and exhaust gas recirculation systems. Engine valves are commonly employed in every type of combustion engine such as gasoline, diesel, kerosene, natural gas, or propane.
In motor vehicle engines, two engine valves are used for each cylinder-an inlet (or intake) valve and an exhaust valve.
Inlet Valve
Fuel is allowed to the cylinder by the inlet valve. When closed, the valve seals the combustion space tightly. The valves are usually made of austenitic stainless steel which is a corrosion and heat-resisting material. Inlet valve is subjected to less heat is usually made of nickel-chromium alloy steel.
Exhaust Valve
The burned gases escape by the exhaust valve. The exhaust valve is usually made of silichrome steel which is an alloy of silicon and chromium with unusual resistance to heat.
The valves used in car engines are termed poppet or mushroom valves. The head of the valve has an accurately ground face with enough margin left to avoid a thin edge.
The angular face is ground on the valve head to make an angle of 45° or 30° to match the angle of the valve seat in the cylinder head. Spring retainer lock grooves are provided at the end of the valve stem.

Premium and Reliable Quality
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.
