VAG PICO® Pilot Operated Control Valve This control valve is controlled by the medium con- veyed for the regulation of pressure and flow rates in service areas without external power supply. Long service life and uncomplicated maintenance is gua- ranteed due to the wear-resistant, corrosion and infiltration-proof seat and threaded steel sleeves that are pressed into the body and prevent corrosion in the control line connections.

But right now, the VAG PICO® Pilot Opera- ted Control Valve works perfectly, reducing pres- sure from 5 to 2.5 bar. Vodokanal Gelendzhik's team is using VAG's equipment and the knowledge of VAG specialists to conduct pressure measurements in other DMAs. These measurements will be the basis for further steps in this town's Pressure Management project. 'Projects like this show that you can provide high- quality services in the housing and utility sector in Russia and that providers of this type of services really want to do good work,' says Stephan Flo- erchinger, Managing Director VAG Russia.
