Spider®-Microvalves
Small, wear-resistant & lightning-fast!

Safety

Spider-Valves are especially recommended for applications with tight specifications regarding availability and reliability. This is possible due to the very long life time of these valves.

Accuracy

The Spider-Valves can be fully customized according to the customer requirements. In this way, Spider-Valves can offer very precise switch time with very high repeatability.

Comfort

Thanks to their very low moving weights, the Spider-Valves are extremely quiet and cause very low vibration. Because of their small size and low energy consumption, they are also ideal for transportable and mobile systems.

Efficiency

Compared to standard valves, Spider- Valves have lighter moving parts and smaller displacement. This results a lower energy consumption and very short switching time.

Spider®-Microvalves

Small, wear-free and fast as lightning

Spider valves are allocated to the micro valve category (outside diameter 7 mm). In technical terms, spider valves are distinguished by the anchor type design. The anchors installed in the micronized valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group.

If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat.

These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. As these valves predominantly featuring cartridge connections have an almost frictionless armature movement, they have a capacity of up to 4 billion actuations, depending upon operation mode.

Spider valves may also be triggered via so-called pulse width modulation. In this application, the electrical power is conducted in impulses to the solenoid assembly group; the duration of these impulses controls the valve’s opening phases and subsequently the desired flow rate. These devices may accordingly fulfill the function of a proportional valve.

The Spider-valve is available in sizes 7 mm, 15 mm and 21 mm.
