This unique functioning principle uses a media separated, direct-acting 3/2-way valve as the pilot valve, while the seal of the main valve is a larger flexible diaphragm or a piston. As soon as the pilot valve opens, the chamber above the piston opens so that the media pressure raises the diaphragm, therefore allowing the media to flow. If the pilot valve is closed, the channel to the outlet side is also closed and the media pressure can build up again through the inlet-side pilot channel. The closing process is additionally supported by the compression spring. A minimal differential pressure between the inlet and outlet is needed for complete opening and closing.
Highest level of functional performance, since the valves are insensitive to corrosion and scale particles
Fast fire extinguishing due to high levels of pressure and large orifices (DN50)
Time and cost savings, as direct installation in the extinguishing line is possible
Highest level of safety performance, since the valve can be opened manually (e.g. in case of a power outage)
No maintenance thanks to a high degree of resistance to the effects of dirt particles
Extreme media resistance against, e.g., fermentation gas and UV radiation – wide range of usages
Maximum corrosion resistance thanks to the media-separated encapsulated solenoid coil
Safe use in the plant, as the solenoid valves offer Zone 1 approvals
No clogging thanks to media separation in the valves.
