Types of Engine Valves:
- Poppet valve:
- is also known as a mushroom valve because of its shape. It is used
to control the timing and quantity of gas flow into an engine. This
is the most widely used valve in an automobile engine. The poppet
valve is given the name because of its motion of popping up and
- It consists of a head and a stem. The valve face usually with an
angle of 30° to 45° is ground perfectly, since it has to match with
the valve seat for perfect sealing.
The stem has a spring retainer lock groove and its end is in
contact with the cam for up & down movements of a valve. In
exhaust, a pressure differential helps to seal the valve. In intake
valves, the pressure differential helps open them.

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 specifications 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 identification 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,Steyr engine cylinder head with high quality and fast
