How it works:
In direct-acting solenoid valves, the solenoid armature opens and closes the valve seat directly. They do not require a pressure difference and function independently of the system pressure. These valves are ideal for applications with small flow rates and low pressures.
When to Choose:
Direct-acting solenoid valves are particularly suitable when there is no or only a small pressure difference. They offer precise control at low pressures or small flows.
Advantages:
Fast response time: The solenoid armature opens the valve directly, enabling fast control.
Independent of the system pressure: These valves also work without a minimum pressure difference.
Simple design: fewer components mean less susceptibility to failure and less maintenance.
Disadvantages:
Limited flow: Not suitable for larger volume flows.
Higher energy consumption: The magnet must fully open the valve, which requires more electrical energy.
"Precision and speed – direct-operated solenoid valves for reliable control even at low pressure."
Typical applications:
Small appliances: e.g. coffee machines or laboratory equipment with low flow rates.
Precision controls: For controlling small fluid flows.
Low pressure systems: systems with no or low pressure difference.
Maintenance and installation:
Low maintenance: The simple design means there are fewer moving parts.
Installation: These valves can be installed in any flow direction as no pressure difference is required.
Example model:
Type AL 01: Direct operated solenoid valve for low pressure and small flow applications.
Summary:
Direct acting solenoid valves offer a fast and precise solution for low-pressure, small-flow applications. They are simple, reliable and ideal for systems with no minimum pressure difference.
