Second, the gas proportional valve is mainly used:

1.Proportional adjustment technology: The proportional valve changes the size of the magnetic field through the proportional valve coil according to the current input by the circuit. The moving shaft (material is pure iron) in the center of the proportional valve coil is moved up and down by the force of the magnetic field, thereby driving and moving the shaft. The connected valve assemblies move up and down, and the ventilation area matched by the spherical surface of the valve assembly and the proportional valve body changes as the valve assembly moves up and down, and finally changes the output pressure of the proportional valve. The output pressure of the proportional valve is proportional to the proportional valve current. increase and increase;

2 Gas pressure stabilization technology: The front pressure of the gas proportional valve is the rated pressure and the highest pressure, and the change of the back pressure of the proportional valve is less than 0.05 times the rated back pressure plus 30Pa.
