Description
Combination air release valve specifically designed for sewage and wastewater systems, constructed from durable ductile iron for enhanced corrosion resistance.
Effectively releases trapped air and prevents vacuum conditions to maintain optimal flow and protect pipeline integrity in sewage applications.
Rated PN16 for pressures up to 16 bar, suitable for medium-pressure sewage and wastewater networks.
Equipped with flanged ends for secure, leak-tight, and standardized connections, facilitating easy installation and maintenance.
