Our company produces the hydraulic valves for ten years.
The hydraulic valves made in very good condition and excellent prices.

The air control reversing valve which

plays the lifting role , is a controlling

 valve . It can do the movement about 

compartment  including lift stop drop .

 It is the two-way air controlled slide valve . 

 When the air controlled pressure loses , 

 the valve could automatly choose stopping

 in order to prevent the compartment drops

 suddenly .
