The AV Stübbe C120 Ball Valves are now available from Air & Hydraulic Systems . Constructed from PE-HD 100 and fitted with NBR seals, these ball valves feature a vacuum-tight housing which makes them maintenance free and resistant to chemical and electrochemical damage.
C120 is available in sizes from DN25 to DN150 and suitable for pressures up to 16 Bar as they are manufactured specifically for drinking water, gas, waste water and sewage applications.
The waste water and gas models of ball valves are specifically designed to be used in underground applications, where the whole valve is hermetically sealed against groundwater, sludge and sand. The spigot ends can be fixed to the pipe using butt welding or electro fusion welding. This minimises the risk of leaking joints.
