Solenoid valves

Solenoid valves play a crucial role in various applications where controlling gas and fluid flows is essential. Here are some important points about solenoid valves:

Electromechanical valves: Solenoid valves are electromechanically controlled valves. This means that the valve is activated by an electromagnetic field, causing the valve to open or close.

Applications: They are widely used in situations where it is necessary to control the flow of gases or clean fluids. Typical applications are found in industrial processes, pneumatics, hydraulics and other systems where fluid or gas flows must be accurately managed.

Types of solenoid valves: Process valves (2/2-way and 3/2-way): These have two and three ports for inputs and outputs, respectively. Pulse valves: Used for periodic power interruptions. Coaxial valves: Have a coaxial structure for specific applications. Proportional valves: Control the flow in proportion to the controlled electric current. Pneumatic valves: Powered by compressed air.

Coding of solenoid valves: Solenoid valves are designated by two numbers, the first indicating the number of ports and the second the number of positions.

Operating principles: Direct: The valve is opened directly by the electromagnet. Semi-direct: The valve can be opened from zero bar pressure. Indirect: The valve opens only when there is a pressure differential.

Characteristics: Fast response time: Ranging from tenths to hundreds of milliseconds. Good sealing properties: Essential for precise control of flows. Durability and reliability: Essential for long-term use in various environments.

Customization options: A wide range of solenoid valves is available to suit different requirements such as pressure, temperature, flow rate, connection style and voltage. Different housing and seal materials ensure compatibility with various media.

Special editions: ATEX certified valves: Suitable for use in explosive environments. Medium-separated valves: Designed to separate the medium from the solenoid coil.

When selecting solenoid valves, it is essential to consider the specific requirements of the application, including chemical compatibility and any certifications required for certain environments.
