The core principle of a proportional valve is that the output—meaning the resulting flow rate or fluid pressure—is directly proportional to the strength of the electrical input signal it receives.
View Details
The working principle of the proportional valve is based on the principle of flow control, the essence of which is to change the cross-sectional area of the medium through the pipeline to change the flow of
