Solenoid Valves
Solenoid valves are electromechanical valves that open or close the flow of liquids or gases controlled by electrical impulses. They consist of a solenoid coil body and a movable armature that actuates the valve when energized. Solenoid valves are used in industrial automation systems, heating and air conditioning systems, and in process industries.
Solenoid valves are not manually operated shut-off valves, not pneumatically controlled valves, and not permanently open flow regulators without electrical control.

Solenoid Valves: Frequently Asked Questions
How do solenoid valves work?
Solenoid valves operate on the electromechanical principle: when energized, a solenoid coil generates a magnetic field that attracts or repels a movable armature. This movement opens or closes the flow path for liquids or gases. When power is disconnected, the armature returns to its original position through a return spring.
In which industries are solenoid valves used?
Solenoid valves are used across various industrial sectors including gas, chemical, petrochemical, and food processing industries. They are deployed in industrial automation systems, heating and air conditioning systems, and process industries. SL Armaturen & Antriebe distributes solenoid valves for these industrial applications.
Which media can be controlled with solenoid valves?
Solenoid valves are designed to control various media, particularly liquids and gases. Depending on construction and materials, they can handle neutral, aggressive, or highly viscous media. The selection of an appropriate solenoid valve depends on factors such as media properties, pressure, temperature, and chemical compatibility.
What are the main components of a solenoid valve?
The main components of solenoid valves are the solenoid coil body and the movable armature. The solenoid coil converts electrical energy into a magnetic field, while the armature executes the mechanical movement. Additionally, the valve body, seals, return springs, and electrical connections are part of a solenoid valve's construction.
What advantages do solenoid valves offer in automation?
Solenoid valves provide fast switching times, precise control, and reliable operation in automated systems. They enable remote-controlled or program-controlled flow regulation without manual intervention. Due to their compact design and easy integration into control systems, solenoid valves are cost-effective and low-maintenance.
