              Proportional solenoid valve is an important means to accurately control flow

and pressure, which can achieve fast and accurate flow and pressure control, and is

widely used in various hydraulic system control. It uses "position feedback" technology

to precisely control the opening degree of the valve, thus achieving outstanding control

results, especially in hydraulic applications requiring high quality.

              Electric gas proportional valve and servo valve according to their functions can

be divided into pressure type and flow type two. The pressure type proportional/servo

valve will linearly convert the electrical signal to gas pressure: the flow type proportional/servo

valve will convert the electrical signal to gas flow. Due to the compressibility of gas, the

movement speed of actuator elements such as cylinders or gas motors is not only

determined by the gas flow rate. It also depends on the load of the executing element.

Therefore, precise control of gas flow is often unnecessary, simple pressure or flow

type proportional/servo valves are not used much, often the combination of pressure

and flow is more widely used.
