Water-activated solenoid valves are industrial devices controlled by electromagnets, serving as fundamental automated components for fluid control, categorized under actuators. They are suitable for mediums like water or liquids and can automate or remotely control the on/off of pipelines carrying fluids such as water, oil, or other liquids. They are used in industrial control systems to adjust medium direction, flow rate, speed, and other parameters. Solenoid valves can be paired with various circuits to achieve desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a role at different positions in control systems. Common types include one-way valves, safety valves, directional control valves, and speed control valves.
