Solenoid valves are electromechanical devices used to control the flow of liquids or gases in a pipe or duct system. They work using an electromagnet that, upon receiving electric current, generates a magnetic field that moves a plunger or core inside the valve, opening or closing the passage of fluid. These valves are widely used in the automation of industrial processes and in systems such as irrigation, HVAC, machinery, and vehicles.

Process and control valves are devices designed to regulate the flow, pressure and other parameters of liquids, gases and materials in industrial processes. Unlike solenoid valves, process and control valves allow for more precise and continuous adjustment of flow conditions, rather than just opening or closing. These valves are used to control various critical variables in process applications such as the chemical, petrochemical, pharmaceutical, food and beverage industries, among others.

Pneumatic and process systems are essential in industrial automation, where they are used to move, control and manipulate different materials and equipment using compressed air and other fluids. These systems provide power, control and precision in a variety of industrial applications.
