Description
The DT-040 combination air valve is designed to prevent problems caused by presence or absence of air in small water supply systems.
This Combination Air valve (Double Orifice) combines air & vacuum large orifices and Automatic small orifices in one single body. The DT-040 discharges air during the filling of the system and admits air while draining.
It continues to release accumulated air from the system while the system is operating under pressure.
