What is the frequency of a proportional solenoid valve? Is the higher the better? How to adjust the proportional solenoid valve

Proportional solenoid valve What is the frequency? Is the higher the better?

Answer: < span style="font-size: 16px;">No, the pneumatic one has 3 times/second and 5 times per second. It depends on what model you have. The hydraulic one has 15,000 times/hour and 7,200 times per hour. It also depends on you. Solenoid valve model.

You need to use a special tool to remove the valve cap, because it can only be adjusted internally. After seeing the valve, adjust the size in the forward or reverse direction. Because the proportional valves of different equipment are different and need to be adjusted according to the corresponding model, and there is a certain degree of danger, so it is best to find professionals to adjust them.

Functionally: flow control valve + solenoid reversing valve = proportional valve

Proportional solenoid valveIt can be controlled by a current similar to brightness adjustment. By changing the current of the coil, the position of the valve core is changed, thereby controlling the flow of the proportional valve. However, the proportional valve spool has a V-shaped groove at the edge of the cut, which makes the opening size of the proportional valve wider. Therefore, compared with the solenoid directional valve, although the proportional solenoid valve has a lower mouth valve flow capacity, it is easier to achieve. The control of small flow, that is, the opening of the proportional solenoid valve can be gradually changed.

Depending on the maximum flow capacity, we can install different valve cores. Meaning these spools come in different shapes, sizes and number of V-grooves. In the switching system, in order to adjust the moving speed of the hydraulic cylinder piston, we need to install a flow valve at the corresponding position. How to use proportional directional valves and proportional pressure valves in a system means that the hydraulic pressure of the system can be controlled by electrical signals. The moving direction, moving speed and output force of the piston can be controlled.
