The classification ways of the reversing valve has several kinds:
Directional control valve is to have 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 valve. Can be divided into manual reversing valve, electromagnetic reversing valves, electro-hydraulic directional control valve, etc.
Directional control valve to the valve according to the directional valve dominated access number is not all the same: two-way, three, four-way, and five and so on. Application is absolutely the wrong body of valve core activities, make the oil transportation, shut off or change the direction of the oil drips, which name hidden hydraulic performance of the component and its driving mechanism of bearing, end, or change direction.
Directional control valve is widely used in petroleum, chemical production, the most commonly used in the synthetic ammonia gasification system. In addition, the reversing valve can also be made the structure of disc type more occasions for small flow rate. Only when the job rotation handwheel transform of the working fluid flow through the disc.
