Vexve’s valves and hydraulic control products were chosen for the A2A Group’s new ring network at San Siro district in Milan. Delivered by Vexve’s partner Sfera Energy Solutions, the choice of Hydrox hydraulic control solution will ensure safe and secure operation of the underground district heating network.
Milan’s district heating system heats over 3000 buildings including many of the historical landmarks and 200,000 apartments in the Milan metropolitan area. In addition to developing the distribution network, A2A Group has been connecting the existing network in different areas of the city to better serve the needs of the vast metropolitan area of Milan.
Two distribution lines were connected through a new ring network located in San Siro district. Vexve’s pre-insulated DN 400 butterfly valves and DN 500 ball valves equipped with Hydrox hydraulic actuators and HCU control units were chosen for the project.
The HCU control units were installed one meter below the street level inside their own appropriate chambers with sufficient room for the operator to descend into the chamber and manually operate the hydraulic control units. The major work on the San Siro ring network was completed in 2017.
