Electromagnetic valves types

Electromagnetic valve is automatic industrial equipment controlled by electromagnetism to adjust the direction, flow, speed and other parameters of the media in industrial control systems. Electromagnetic valve is controlled by the electromagnetic effect, and the main control is by the relay. Thus, electromagnetic valve can be used in different circuit with the highly precision and flexibility.
There are a variety of  types, varieties of electromagnetic valves in different locations of the control systems to play a important role , the most commonly used is the one-way valve, safety valve, directional control valves, speed control valve.
