A.R.I
Developed by Aran, the D-040 Air Valve “BARAK” combines both a kinetic and an automatic air valve as one unit in one body. The valve’s unique characteristics are the gradual release of air (thus preventing local water hammer), effectiveness at low pressure and working pressure, and its self-cleaning ability. The combination valve releases air when the system is being filled, enables entry of air when the system is being emptied and releases trapped air when the system is under pressure.
