When water has been treated in a water treatment plant, it will be pumped to the consumer via a wide distribution network. This network is made of different kinds of pipe material; typically ductile iron, PVC, steel or PE. A distribution network usually functions at a relatively low pressure, but water pressures may vary in a distribution system. The pressure just needs to be high enough for the water to reach the consumers living in the highest places in relation to the pumping station. In mountainous areas, the distribution net is built up in pressure zones, separated by means of pressure reducing stations, gate valves and check valves. Zenzele Valves offers various types of valves, hydrants and accessories for all kinds of pipe material and operating pressure.
