The new A.R.I M-040 combination air valve is designed to prevent problems caused by discontinuous or erratic water supply:
• Erroneous water metering.
• Damage to the spinning components of the water meter.
• Vibrations and water hammer in the pipeline and water meter.

Main Features
Combination Air Valve with three functions of operation:Discharges air at high flow rates while the pipeline is filled withwater. Admits air into the pipeline at high flow rates during system drainage and water column separation. Continuously releases entrapped air that accumulates in the pipeline when the systemis under pressure.
• Working range: 3 -150 psi
• Connections: Threaded 1/2" NPT
• Temp. : Up to 140° f
• Materials: The air valve is made of corrosive resistant materials.
• Integral shut-off valve: An innovative built- in shut off valve inthe valve cap enables the isolation of the air valve orifice with nointerference with water flow in the pipe.
