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.
