Description
The new A.R.I 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 Kinetic large orifices and Automatic small orifices in one single body. The development and production of this revolutionary valve is based
on many years of experience and innovative R & D.
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.
