What Is a Shunt Valve?

Shunt valve is also called speed synchronization valve. It is the general name of diverter valve, header valve, one-way diverter valve, one-way header valve and proportional diverter valve in hydraulic valve. Synchronous valve is mainly used in dual-cylinder and multi-cylinder synchronous control System. There are usually many methods to achieve synchronous movement, but the synchronous control hydraulic system using the diverting header-synchronous valve has many advantages such as simple structure, low cost, easy manufacturing, and high reliability. Therefore, the synchronous valve has been obtained Wide application. The synchronization of the shunt collector valve is speed synchronization. When the two or more oil cylinders respectively bear different loads, the shunt collector valve can still ensure its synchronous movement.

The role of the diverter valve is to make

As shown in the figure is the structure principle diagram of the equal volume diverter valve, which can be considered as two series pressure reducing flow

The figure shows the principle diagram of the equal volume collector valve, which is basically the same as the feedback method of the diverter valve, with the following differences:

(1) The diverter valve is installed on the oil return path of the two actuators, and the oil return flows of the two loads are brought together to return oil; ^[2]

Divided by adjustment method: fixed

The difference between manifold and diverter valve:

1) The collecting valve is installed on the oil return path of the two actuators, and the oil return flows of the two loads are brought together to return the oil; ^[1]

2) The two flow sensors of the diverter valve share inlet pressure. The larger the flow rate of the flow sensor is, the lower the outlet pressure is; . Therefore, the pressure feedback direction of the collector valve is exactly the opposite of that of the diverter valve; ^[1]

3) The collecting valve can only ensure that the actuator is synchronized when the oil returns. ^[1]
