How to choose the right hydraulic solenoid reversing valve

Hydraulic solenoid valve as a common hydraulic control element, its model specifications are more, in the selection should consider the flow rate, control mode, function, voltage and other specifications parameters.

YouQuen introduced 5 methods in order to help you choose the right hydraulic solenoid reversing valve.

Selection should consider the following factors:

1. Control Mode

Hydraulic solenoid-operated reversing valve is generally divided into two control methods: solenoid and manual, which should be selected according to the convenience of control and system automation level.

2. Pressure and Flow

The pressure and flow rate of the hydraulic solenoid-operated reversing valve should meet the following requirements.

(1) should make the working pressure and flow rate of the system is less than the rated working pressure and flow rate of the valve, otherwise it will lead to abnormal action.

(2) The rated flow rate of the solenoid-operated reversing valve is relatively small, and the electro-hydraulic reversing valve should be used when the working flow rate of the system exceeds its rated flow rate.

(3) The back pressure at the T-port of the oil outlet cannot exceed the maximum allowable value, otherwise it will lead to difficulties in reversing the solenoid-operated reversing valve.

3. Valve Spool Function

The different reversing functions of hydraulic solenoid-operated reversing valves are realized by different spool designs. The correct spool function should be selected according to the working requirements of the hydraulic system. 

4. Ommutation Accuracy and Smoothness

When the work A and B ports are blocked, the reversing is easy to produce hydraulic shock, but the reversing accuracy is high, when the A and B ports are connected with the return port, the actuating element is not easy to brake during the reversing process, but the hydraulic shock is small.

5. Starting Smoothness

Different neutral function of hydraulic solenoid reversing valve start performance is different, in the neutral if a cavity of the hydraulic cylinder and the oil tank, start because there is no hydraulic oil to play a buffer role, easy to lead to unstable start.

The above is the hydraulic solenoid valve in the selection of several aspects need to pay attention to.
