First, how to adjust the pressure of hydraulic solenoid valve

This solenoid valve cannot directly adjust the pressure, because it is itself a valve that can control the direction of the fluid. To control its pressure, we can use a reducing valve or a relief valve. Once installed in place, it can be used to control its pressure level.

This hydraulic reversing valve controls the direction of the fluid, is a direction control valve, plays the role of on and off, change the direction. Generally used in some mechanical devices, such as hydraulic cylinder control, you need to use this solenoid valve. The whole operating system is relatively simple, the price is not particularly high, can respond quickly, lightweight.

Second, what are the classifications of hydraulic solenoid valves

1, the hydraulic solenoid valve is also called the direction control valve, if divided according to the use, there are relief valves, pressure reducing valves and so on. It can achieve the role of setting the pressure and ensure the constant pressure. There is also a pressure reducing valve, which controls the branch circuit, so that the pressure function is different, to achieve a stable output state.

2, in addition to the flow control valve, such as throttle valve, speed control valve, diverter valve and so on. There is also a direction control valve, which is divided into one-way and reversing. If it is the former, the liquid can only be allowed to flow in one direction in the pipe. If it goes the other way, it gets cut off.

3, if the valve is selected, it can not only change the on-off relationship, but also change the direction of the fluid by installing three-way, four-way, and so on.
