A.R.I. D-070 P is a unique multi-function Dynamic Combination Air Valve, operating without a float; utilizing a rolling diaphragm principle. Its unique structure allows the valve to discharge air from the water system gradually, in a controlled manner to prevent slam or local upsurge. The valve is normally closed when the line is not
pressurized, thus prohibiting infiltration of foreign particles or insects into the system.

Dynamic Combination Air Valve, operating without a float

Technical Specifications
- Working pressure range 0.2-10 bar (PN 10) | 0.2-16 bar (PN 16)
