Water Supply Fittings for the Building Technology Sector

Our pressure reducing valves with potable water approvals, both with threaded or flange connections do not only cover all classic areas of the water supply sector: They are often used for applications in sprinkler systems, in water-treatment or desalination plants. The materials of all wetted parts do not only fulfill the stringent national DVGW regulations but also those in France (ACS), the UK (WRAS) and Norway (SINTEF).

PRESSURE REDUCING VALVES 6ERES 9000

made of lead-free gunmetal with threaded connections

The first Goetze fitting made of plastic has been developed for environmentally aware and health-conscious users. The lead-free pressure reducing valve housing does not release any harmful substances into the potable water and is corrosion-resistant for all water qualities. At the same time, the avoidance of heavy metals protects the environment. The valve insert is made of high-quality plastic from the medical technology sector and offers convincing cavitation-, temperature- and media resistance. The flow rate of the pressure-reducing valve has also been rated for maximum output – flow optimization permits a higher maximum flow rate and physical effects in the valve can create a higher flow rate with the same pressure drop. The integrated 160 pm fine screen insert protects the fitting and downstream installation from dirt particles and is easy to clean without the valve insert having to be removed and the output pressure reset. The degree of contamination can be seen through the transparent filter cup. Another feature is the setting scale visible from 2 angles. This makes the setting process even more convenient by displaying the current set pressure in every position. This means that the setting can also be made without a pressure gauge, special tool, or operating pressure.

Particularly in the case of valves which are employed in potable water installations, we do not accept any compromises regarding the materials used. Only the highest quality materials suitable and approved for potable water applications are used in these valves. These apes of safety valves with diaphragm are installed in the cold water pipe before the hot water heater to protect it from inadmissible overpressure.

made of gunmetal, straightway form with threaded connections

The combination of the shut-off valve, strainer, dirt trap, and diaphragm safety valve in the 669sWK version, as well as the additional pressure reducing valve in the 669pWK, in a space-saving body, guarantees adherence to the mandatory order for all valves required in drinking water circuit heaters. This eliminates the necessity for time-consuming individual installation. The body made of gunmetal guarantees excellent resistance to the most varying qualities of potable water.

made of stainless steel and gunmetal with flange connections

Fittings often require flange connections. This is the exact reason for our series in the nominal diameter ranges of DN 15 up to DN 100. Besides the standard versions of these pressure reducing valves made of stainless steel and gunmetal, the valves are also available in nominal diameters from DN 20 to DN 50 in high-pressure and a low-pressure version. Upon re- quest, we can also equip the stainless steel pressure reducing valves for various pressure ranges with stainless steel pressure gauges. For the highest service-friendliness also in the case of the flange versions, a replacement internal cartridge with integrated dirt trap is available.
