The reversing valve has two or more flow form and two or more oil control valve in the direction of the mouth. It is the valve to realize the communication of the hydraulic oil flow, cut off and the reversing, and pressure unloading and sequential control. It can be divided into the manual reversing valve, electromagnetic reversing valves, electro-hydraulic directional control valve, etc.
The reversing valve has many different channels : two-channel, three-channel, four-channel, five-channel and so on. Use the absolute movement of the wrong body of the valve core, making the oil transportation shut off or change the direction of the oil drips, which makes the hydraulic performance of the component and its driving mechanism of bearing, end, or change direction.
The reversing valve is widely used in the petroleum, chemical production,it is most commonly used in the synthetic ammonia gasification system. In addition, the reversing valve can also be made with the structure of disc type more in the occasions for small flow rate. When it works, you only need to rotate the handwheel to transform the working fluid flow through the disc.
