The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cutting off and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. It can be divided into manual reversing valve, electromagnetic reversing valve, electro-hydraulic reversing valve and so on.

When working, the drive shaft is rotated by the drive transmission mechanism outside the valve, with the shaking crank arm, and the valve plate is started, so that the working fluid sometimes leads from the left entrance to the lower exit of the valve, and sometimes changes from the right entrance to the lower exit, so as to achieve the purpose of periodic change of flow direction.

This kind of change valve is widely used in petroleum and chemical production, and is most commonly used in synthetic ammonia gas making system. In addition, the reversing valve can also be made into a disc type structure, which is mostly used for small flow situations. When working, just turn the hand wheel through the valve disc to change the flow of the working fluid

The operation is accurate, the degree of automation is high, the work is stable and reliable, but the driving and cooling system needs to be attached, and the structure is more complex; The valve flap structure is simpler and is mostly used in the production process with small flow.
