Underground air valve for wastewater fig. SCF-U

The air valve ensures correct operation in dirty water systems by allowing air pockets to escape under working conditions, and large volumes of air to be released and admitted during filling and venting. Thanks to its construction it needs no chamber or isolating devices, making it the ideal choice where installation costs must be reduced, or simply where excavation or building a chamber is not possible.
