Negative Pressure Elimination Valve for Sewage
Astral’s Air Admittance Valves are designed to address the issue of negative air pressure that occurs in sewage systems when sanitary facilities are utilized. This negative pressure can lead to the siphons losing water due to the flow of sewage. By providing an air supply to the sewage system, air admittance valves effectively counterbalance negative air pressure. Astral Air Admittance Valves are manufactured in accordance with the latest European standards and are capable of operating within a temperature range of -20°C to +60°C.
