AVK Wins An Impressive Order Based on A Product and Solution Package - Series 859 control valves optimizing pressure management of water distribution
It is well-known that one of the major factors that influence the leakage rate is a high pressure in the distribution system. Most pipe bursts occur not only because of high pressure but rather due to ongoing pressure fluctuations that force the pipe to continually expand and contract, resulting in stress on infrastructure. Therefore, it is critical to reduce to a low constant pressure in the system.
AVK control valves Series 859 are used to provide optimum pressure and flow conditions at any time. They maintain certain pressure, flow or level regardless of changes in the supply network, and therefore help reduce water losses and contribute to efficient water supply.
AVK valves are intelligent
The AVK control valve series 859 mounted with the ACMO PMD communication device is a local controller that can provide a wide range of control applications in a SMART pressure management system. The features are a highly accurate control and auto-adaptive PID in order to fit the valves for a multitude of different hydraulic conditions. The ACMO PMD is supplied with pre-configurable hydraulic control functions and data-logging features, that enable the operator to preset conditions for flow and pressure. The unit will communicate with flow meter and adjust the pressure according to flow regardless time of the day.
AVK are currently working together with Georgia Water and Power for the supply Series 859 control valves. The valves are to be installed as part of a leakage reduction initiative in Tbilisi, Georgia’s capital city. Following the initial technical discussions and benefits of S859 over other control valves in Tbilisi. Various trials were performed and videos and data logging results were provided to GWP to ensure the customer was fully satisfied with the specifications and operational performance.
After installation 235 Series 859 PRVs, GWP saved 28million cubic meters of water per year, Consumption of electricity for water treatment and distribution is reduced by 8-10%. Planned installation of more than 500 PRVs series 859, DN50-300 PN16 to reduce water loss, Expected reduction of pumped water is 58,000,000 m3 /year, the saving alone on producing this amount of water is nearly 6.4 million USD per year. AVK were awarded the contract for the supply of the control valves despite serious competition from cheaper competitors, but GWP were very clear their requirements were for high quality valves with excellent support and therefore acknowledged the benefits of using AVK and their Series 859 valves. AVK intelligent control valve has been a proven solution for reducing leakage and burst frequency, bringing optimal and cost effective pressure control to your network. It is also a vital tool for smart networks!
