GTS - Global Technical Solutions Solenoid Valve DN 3,0 mm, 18,0 bar DC

A solenoid valve is an electromechanical valve that uses an electric current to control the flow of a liquid or gas. It works by using a magnetic field generated by a coil of wire (the solenoid) to move a plunger or armature, which opens or closes the valve. These valves are widely used to automate the control of fluid flow in various applications, from household appliances to industrial machinery. 

Here's a more detailed explanation:

Components:

• Solenoid:
• A coil of wire that generates a magnetic field when energized by an electric current. 
• Plunger/Armature:
• A ferromagnetic (magnetic) piece that moves linearly within the solenoid coil. 
• Valve Body:
• Contains the valve seat and other parts that control the flow of fluid. 
• Spring:
• A spring is often used to return the plunger to its default position when the solenoid is de-energized. 

How it works:

1. 1. De-energized:
2. When no current flows through the solenoid coil, the plunger is typically held in a position by a spring, keeping the valve either open or closed, depending on the valve design (normally closed or normally open).
3. 2. Energized:
4. When an electrical current is applied to the solenoid coil, it creates a magnetic field. This magnetic field attracts or repels the plunger, causing it to move.
5. 3. Valve Operation:
6. The movement of the plunger opens or closes the valve, controlling the flow of fluid. 

Types of Solenoid Valves:

• Direct-acting:
• The magnetic force directly acts on the valve closure element (plunger or diaphragm).
• Pilot-operated:
• The magnetic force controls a small pilot valve, which in turn controls a larger valve that handles the main fluid flow. 

Common Applications:

• HVAC systems: Controlling the flow of refrigerants, water, and air. 
• Industrial automation: Controlling the flow of various liquids and gases in manufacturing processes. 
• Washing machines and dishwashers: Controlling the flow of water. 
• Medical equipment: Precise control of fluids in medical devices. 
• Automotive industry: Controlling fuel flow, air suspension, and other systems. 

Advantages of Solenoid Valves:

• Fast response time: Can switch on and off quickly.
• Remote control: Can be operated remotely using electrical signals.
• Reliable and durable: Offer long service life and high reliability.
• Compact design: Can be easily integrated into various systems.
• Relatively low power consumption: Especially pilot-operated valves.
