Sähköventtiilit

Sähköventtiilit, also known as solenoid valves, are electromechanically operated valves. They use an electric current to control the flow of liquids or gases. A solenoid is an electromagnet that, when energized, creates a magnetic field. This field moves a plunger, which in turn opens or closes the valve, allowing or blocking the flow of the medium.

These valves are widely used in various applications due to their fast response times, reliability, and ability to be easily automated. Common uses include industrial automation, process control systems, HVAC systems, automotive applications, and even household appliances like washing machines and dishwashers. They are essential components for controlling fluid and gas flow in automated systems.

Sähköventtiilit come in various types, including direct-acting, pilot-operated, and latching designs. Direct-acting valves are simple and consist of a solenoid coil and a plunger that directly opens or closes the valve orifice. Pilot-operated valves use the system pressure to assist in opening or closing the valve, making them suitable for higher pressure applications. Latching valves retain their position after the electrical signal is removed, requiring a second pulse to change their state, which is useful for power-saving applications.

The selection of a sähköventtiili depends on factors such as the type of fluid or gas, operating pressure, flow rate requirements, temperature, and the electrical specifications of the control system. They are a crucial element in modern automation, enabling precise and efficient control of fluid and gas circuits.
