What electronic valve does Lamian Noodles machine use?

The electromagnetic valve is used for the electromagnetic valve of the noodle making machine, which is a fast noodle making machine. A patent has been applied: when the noodle barrel is not completely pushed into the machine, the induced pressure of the pressure regulating valve is greater than the preset value, and the electromagnetic valve reverses the oil path, so that the hydraulic cylinder stops pressing down and returns to the original position, which improves the safety of use. The design of the rotating device of the utility model makes the machine more flexible and reduces the space occupation.
