Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve body technology, and in particular to an electromagnetic valve body control system. Background Technology

[0002] The control methods of solenoid valve bodies include four main types: manual control, mechanical control, hydraulic control, and electrical control. Among them, electrical control includes switch control, proportional control, and servo control. However, regardless of the type of electrical control, the solenoid valve body needs to be connected to the controller, and the controller sends control signals to the external actuator connected to the solenoid valve body. Since solenoid valves typically need to be connected to many external actuators, and the physical connection of a large number of solenoid valves to the controller would cause large injection molding machines to spend a lot of time on electrical installation, which is time-consuming and labor-intensive; in addition, the limited number of wiring pins of the controller restricts the expansion of solenoid valves.
