1 HS10S-FA Water station Product specification sheet Range of Application Medium Drinking water Inlet pressure Max. 16 bar Outlet pressure bar Installation position Horizontal with filter bowl downwards Connection size DN 65 - DN 100 Flanges on inlet and outlet Flanges PN16 acc. to DIN86021 / ISO , EN The filter is constructed for drinking water installations. In case of a process water application the filter has to be proven individually. Technical Data Operating temperature Max. 65 C Nominal pressure PN16 Minimum pressure drop 1.0 bar Opening pressure check valve ca bar Operating pressure Min. 2.0 bar Max bar Diaphragm pressure loading Max. 9.0 bar Connection size DN 65 - DN 100 Application Water stations of this type are suitable for installations with high water demand. They can be used in large residential buildings, for central water supply as well as in commercial, industrial or similar applications. The unit consits of all recommended devices for protection as check valve, reverse rinsable filter and pressure reducing valve. The check valve protects the mains water system against back pressure, back flow and back syphonage of health threatening liquids. The reverse rinsable flange filter prevents the ingress of foreign bodies, for example rust particles, strands of hemp and grains of sand. It contains a highly efficient reverse rinsing filtering system and can be retrofitted with the Z11AS fully automatic reverse rinsing actuator and the DDS76 differential pressure switch. The pressure reducing valves protects installations against excessive pressure from the supply. Pressurisation damage is avoided and water consumption is reduced. Additional reduction of the operating pressure and maintaining it at a constant level minimizes flow noise in the installation. Special Features DIN/DVGW-certified check valve and filter Filter insert fully replaceable Filtered water supplied even during reverse rinsing Patented reverse rinsing system - fast and thorough cleaning of the filter with small amount of water Fully automatic reverse rinsing with retrofittable automatic reverse rinsing actuator Z11AS and differential pressure switch Red bronze construction (filter) resp. powder coated cast iron (check valve and pressure reducing valve) gives high level of corrosion protection Standardised discharge connection Non-rising stem for setting outlet pressure and position indicator on spring bonnet on pressure reducing valve The adjustment spring of the pressure reducing valve is not in contact with the potable water Inlet pressure balancing - fluctuating inlet pressure does not influence outlet pressure 1

2 Construction The water station comprises: Check valve with o Housing and housing end casing with flanges o Check valve insert o Test and drain plugs o Disc, guide, spring, disc lip seal ring Fine filter with o Housing with flanges o Pressure gauge o Fine filter in brass filter bowl o Ball valve with lever and drain connection Pressure reducing valve with o Housing with PN16 flanges per ISO7005-2, EN o Spring bonnet with adjustment screw oadjustment spring ocartridge insert o Pressure gauge Materials Check valve o Grey cast iron housing end and housing o Stainless steel screws and nuts o Stainless steel disc o Stainless steel spring o EPDM for lip seal ring Fine filter o Red bronze housing and filter bowl o Stainless steel, red bronze and brass inner parts o Stainless steel fine filter Pressure reducing valve o Housing made of ductile cast iron (EN-GJS EN1563), coated with PA (Rilsan) o Spring bonnet made of ductile cast iron (EN-GJS EN1563), coated with PA (Rilsan) o Cartridge insert made completely of low-lead (<2.2% acc. to DIN part 6) brass with stainless steel valve spindle o Spring steel adjustment spring o Diaphragm and seals made of EPDM o Groove ring and sealing disc made of high-quality PU o Stainless steel thread rod and nuts Method of Operation Spring loaded check valves have a moving seal disc which is lifted off the seat by a greater or lesser amount depending on the flow rate through the valve. If the flow falls towards zero, then the spring pushes the disc back onto the seat and seals the waterway. To ensure continuing correct function it is recommended that check valves be regularly checked and maintained (as specified in EN 1717). The filter insert is divided into two parts. In the filtering position, only the lower, larger section is rinsed through by water jets from outside to inside. The small upper section does not come in contact with unfiltered water. When the ball valve is opened for reverse rinsing, then the whole filter insert 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 filter section, then the rotating impeller and the main filter from inside to outside, i.e. the filter is reverse rinsed with filtered water. In that way the upper filter is also cleaned by jets from the impeller. The filter automatically switches back to the operating position when the ball valve is closed again. Options HS10S-...FA =Standard version with flanges PN16, Filter mesh size 100μm Connection size Spring loaded pressure reducing valves operate by means of a force equalising system. The force of a diaphragm operates against the force of an adjustment spring. If the outlet pressure and therefore diaphragm force fall because water is drawn, the then greater force of the spring causes the valve to open. The outlet pressure then increases until the forces between the diaphragm and the spring are equal again. The inlet pressure has no influence in either opening or closing of the valve. Because of this, inlet pressure fluctuation does not influence the outlet pressure, thus providing inlet pressure balancing. 2

4 HS10S-FA Water station Installation Example Installation Guidelines Install in horizontal pipework with test and drain plugs and filter bowl downwards and spring bonnet upwards o This position ensures optimum draining and filter efficiency Install shutoff valves o Shutoff valves provide optimal serviceability Ensure good access o Pressure gauge can be read off easily o Simplifies maintenance and inspection The installation location should be protected against frost Fit immediately after water meter o Corresponds to DIN 1988, Part 2 Provide a straight section of pipework of at least five times the nominal valve size after the pressure reducing valve (in accordance with DIN EN806 part 2) Typical Applications Water stations of this type are suitable for use as a safety device on water installations as well as for district water supply mains as specified in EN They can also be used for commercial, industrial or similar water supply systems. The following are some typical applications: After a water meter As a safety device up to liquid category 2 of EN 1717 Upstream of water heating installations In transfer points for central water supply systems when drainage is available If the downstream system includes appliances which must be protected against dirt If the static pressure exceeds the maximum permissible value for the system If pressure fluctuations in the downstream system must be avoided To reduce the water consumption Possible applications e.g. in laundries, refineries, district heating systems or central water supply systems 4
