Description
The 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
• Working pressure range: 3 - 150 psi.
• Testing pressure: 250 psi.
• Working Temperature: 140° f.
• Maximum working temperature for short time period: 194° f.
• Combination Air Valve with three functions of operation: Discharges air at high flow rates while the pipeline is filled with water. 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 system is under pressure.
• Connections: Threaded 1/2" NPT
• Materials: The air valve is made of corrosion resistant materials.
• Integral shut-off valve: An innovative built- in shut off valve in the valve cap enables the isolation of the air valve orifice with no interference with water flow in the pipe.
• Integral air trapping N.R. valve.

Valve Selection
Option: One-Way - Air discharge only.
