Types of Engine Valves:
There are 3 different types of engine valves as follows:
- Poppet valve
- Sleeve valve
- Rotary valve
- #1 Poppet Valve
- It 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 down.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.
#2 Sleeve Valve
The sleeve valve as the name implies is a tube or sleeve that fits
between the piston and the cylinder wall in the cylinder of an internal combustion
engine, where it rotates/slides.
Ports on the side of the sleeves come into alignment with the
cylinder’s inlet and exhaust ports at the appropriate stages in the
engine’s cycle.
The inner surface of the sleeve forms the inner cylinder barrel in
which the piston slides. The sleeve is in continuous motion
allowing and driving out the gases by virtue of the periodic
coincidence of port cut in the sleeve with ports formed through the
main cylinder casting.
#3 Rotary Valve
There are many types of rotary valves. The figure shows the
disc-type rotary valve. It consists of a rotating disc that has a
port. While rotating, it communiafter market dieseles alternately
with the inlet and exhaust manifolds.

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.
