data for acquisition in any remote control or another data collection method. The NeoFlow manual pilot can be replaced by a remotely controllable and programmable “smart” pilot, connectable with the most common data transmission systems. The flexibility that characterises installation, handling, and adaptation to existing spaces is also found in its performance. The combination of axial flow design and polymer material make the valve much less prone to cavitation damage, even at high pressure differential. Thanks to the materials chosen and the design of the valve, reliability is very high and maintained for years. Another considerable benefit of NeoFlow is the reduced maintenance costs. Compared to traditional metal valves, it features only two moving parts. The maintenance of NeoFlow is carried out in under an hour. The calibration of the manual

pilot is very simple and quick. Once the necessary downstream pressure has stabilised, it is then constantly maintained, even when facing sudden consumption, such as from the opening of hydrants or other unscheduled consumption. If there is an opening of the valve, the necessary flow rate at the preset pressure is maintained. NeoFlow does not only regulate downstream pressure. We can also apply the valve for possible regulation of upstream pressure, as a support function, to regulate the level of a tank or the pressure based on the flow rate. GF Piping Systems also offers prefabricated kit solutions. The valve is already installed in a system equipped with filters and valves, made of plastic material, which can be installed directly in the network thanks to the exits tensile resistant universal MULTI/JOINT fittings that adapt to the existing pipe. With its reduced weight the NeoFlow polymer valve has less need for space and offers lower maintenance and monitoring costs is an environmentally friendly solution, saving valuable resources. It is easy to use, technologically advanced, and offers a great deal of efficiency and reliability over time.

The PRV can be directly installed in the water system

Even in conditions of extreme flow rates, the valve behaves reliably at a very low opening, as well as with maximum opening. The axial flow technology considerably reduces the turbulence of the downstream flow, and thanks to the reduced space needed, a flow measuring equipment can be installed directly next to the outgoing flow with no harmful effect on accuracy. With NeoFlow valve, the “wafer-style” assembly is achieved by inserting the valve between two flanges with threaded rods and bolts to close the body, the speed and simplicity of installation make it a very convenient choice in the design phase. The NeoFlow weighs about 40 per cent less than traditional metal valves. The extreme lightweight and reduced dimensions allow installation in confined spaces. Olivier Narbey, senior business development manager water network performance at GF Piping Systems, said: “Existing water networks often lack the space for retrofitting, causing high installation costs. For example, in a tight manhole, only one person fits through. For retrofitting a metal pressure regulating valve, more than one person is necessary, as the valve’s weight is a big issue. “NeoFlow PRV was therefore developed to solve these problems. The state-of-the-art technology polymer PRV is three times more compact than a standard metal PRV and up to nine times lighter, so it ensures safe and hassle-free installation, even in the tightest of spaces. The installation process also becomes extremely cost-effective on a newly built valve installation, compact pre-fabrication saving up to 40 per cent of the costs.” Retrofit operations can be carried out easily since the NeoFlow valve is inserted in the same spaces as the previous valves, leaving extra space for the possible insertion of flow measurement instruments. The saved space can facilitate the insertion of any sensors in the network for the detection of parameters necessary for checking the quality of the water. These parameters can converge with the pressure reading
