The FS870S is the revolutionary control device for pressurized enclosure
systems (Ex px- systems) for uses within the Ex- Zones 1 and 21.
The pressurized enclosure system F870S consists of the control
unit FS870S and a solenoid valve at least.
Additional Ex i- user interfaces
Ethernet interface are optional components to scale up the power of this Ex p- system.
Based on the development and introduction of the proportional valve
technology for pressurized enclosure systems (Gönnheimer, patented system
F850), the FS870S contains an additional, active, proportional outlet valve.
