Sprinkler Saves


The Easiest way to meet NFPA 13

The PURGEnVENT Model 7910MAV Manual Air Venting Valve is a ½" ball valve that features a mesh strainer and ball float. The M7910MAV is a one-piece isolation valve that allows air to vent from the fire protection system while it is being filled with water.

To remove air while the system is being filled open the valve until water reaches the M7910MAV, then close the valve. When the system is in operation the M7910MAV can be opened and closed in rapid succession to vent any remaining air. Leave the valve in the closed position during normal system operation.

NOTE: Factory Mutual does not offer an approval standard for manual air venting valves.
