FK09S
Filter combination with reverse rinsable fine filter
clear filter bowl and balanced-seat pressure reducing valve
APPLICATION
The FK09S filter combinations comprise a reverse rinsing filter and pressure reducing valve in one appliance. They ensure a continuous supply of filtered water. The fine filter stops the ingress of foreign bodies, for example, rust particles, strands of hemp, and grains of sand, and thus reduces the probability of corrosion. The pressure-reducing valve prevents pressure damage and reduces water consumption.
All individual units correspond to the requirements of current DIN/DVGW specifications. Technical features of each unit also apply to the combination assembly.
SPECIAL FEATURES
- Filtered water supplied even during reverse rinsing
- Patented reverse rinsing system – fast and thorough cleaning of the filter with a small amount of water
- Memory ring indicates when the next manual reverse rinsing is due
- Automatic reverse rinsing actuator with bayonet the connector can be retrofitted
- Shock-resistant clear synthetic material filter bowl enables easy checking of filter contamination
- Inlet pressure balancing – no influence on the outlet pressure by fluctuating inlet pressure
- Filter and complete filter bowl are replaceable
- The valve insert is of high-quality synthetic material and can be fully exchanged
- Large filter surface
- Standardized discharge connection
- All materials are KTW approved

METHOD OF OPERATION
The filter combination combines reverse rinsing filter and pressure reducing valve in one appliance.
The filter insert comprises an upper part and a lower combination section. When in the „filtering“ position, the small upper filter is closed so that the water can only pass through the main filter from the outside to the inside. When the ball valve is opened for reverse rinsing, the filter is pushed downwards until the water supply to the outer side of the main filter is stopped. Simultaneously, the water flow is opened to the upper part of the filter. The water needed for cleaning the filter passes through the upper sieve, the rotating impeller, and the main filter from inside to outside. By this means, the filter is fully cleaned over its whole surface area at the full inlet pressure. The filter automatically switches over to the operating position when the ball valve is
closed again.
The integral pressure reducing valve functions on a balanced force principle whereby the force exerted by a diaphragm is balanced against the force of an adjustment spring. The inlet pressure has no influence on the opening or closing of the valve. Inlet pressure fluctuation does not
therefore affect the outlet pressure.

INSTALLATION GUIDELINES
Setup requirements
- Install in horizontal pipework with filter bowl downwards
– This position ensures optimum filter efficiency - Install shut-off valves
- Ensure good access
– Pressure gauge can be read off easily
– Degree of contamination can be easily seen with a clear filter bowl
– Simplifies maintenance and inspection - The installation location should be protected against frost
- Related to the EN 806-2 it is recommended to install the filter immediately after the water meter
- In order to avoid flooding, it is recommended to arrange a permanent professionally dimensioned wastewater connection
