- direct acting solenoid valves
The valve opens or closes directly by the magnetic system.
Operation pressure or pressure difference is not necessary.
The valve operates from 0 bar. The sealing element has to
be lifted off the seat by magnetic power against the media
pressure and spring pressure.
- pilot operated solenoid valves
The valve needs the pressute of the media to open or to close.
The media pressure difference lifts the sealing element. This actuation
type enables the use of coils with small power in applications wiith
high flow rates and high pressure.
force pilot operated solenoid valves
This actuation type is a combination of direct acting and pilot
operating valves. Both advantages (no pressure difference and
high flow rates / high pressure) are united.
The valve operates from 0 bar. The drive opens a pilot control
nozzle and lifts the sealing element, directly or supported by
pressure difference.
- external controlled valves
The valve is controlled by an external pilot valve, which is installed
either directly or in the control line. With clean control media
(e.g. air, hydraulic oil) the valves can be controlled independently
of high temperatures, high pressure and dirty media.
