Product Description

Product Description

The operation of an air/vacuum valve is similar to the air release valve except that the orifice diameter is considerably larger and will not open under pressure. An air/vacuum valve is normally open and is designed to vent large quantities of air through the orifice. As water enters the valve during filling of the system, the float will rise closing the orifice. Air/vacuum valves once closed WILL NOT REOPEN TO VENT AIR while the pipe-line is operating under pressure exceeding atmospheric pressure or if water is present.

Product Features

Pressure & Vacuum relief in a water piping system

High capacity Venting & Vacuum relief for piping system protection

Increase efficiency of water transport in a piping

Prevent overflowing

Easily cleaning the Inside of air/vacuum valve

Product Specifications

This MAV type products describes 1/2-in.(13-mm) through 30-in.(750-mm) for flanges/orifice of air/vacuum valves and The valves are designed for use in water systems with maximum working pressures of 300 psig (2,070 kPa [gauge]) and water temperatures ranging from above freezing to maximum of 125%(52). - AWWA C512/AWWA M51

Product Use

Air/Vacuum Valves, also called large orifice valves, are designed to exhaust large quantities of air automatically during pipeline filling and to admit large quantities of air automatically when the internal pressure in the pipeline drops below atmospheric pressure.
