AGF Manufacturing Inc., which specializes in fire-sprinkler products and components, has launched a new line of air-venting valves called PURGEnVENT, which can be used in self-storage facility sprinkler systems and other applications. The valves are designed to remove excess air from sprinkler pipes to reduce corrosion, which can cause systems to fail during a fire.
Corrosion can occur when oxygen becomes trapped within a pipe and interacts with water or moisture. AGF valves are designed to purge and vent the trapped air. The company developed the line to meet new venting requirements put in place last year by the National Fire Protection Association.
The line includes three models and offers automatic and manual units, according to a company press release.
Model 7910MAV is a manual air-venting valve that uses a half-inch ball with an integral strainer and ball check to allow for venting while the system is filling.
Model 7900AAV is an automatic air-venting valve that uses a 1-inch ball with an integral-isolation valve, strainer, purge valve and automatic air vent to allow rapid purging of air while the system is filling. Automatic venting occurs once the system is operational, according to the release.
Model M7950ILV is an inline air-venting valve developed for systems with location restrictions. The valve uses an air/water separation chamber with an air scoop to separate air from water during filling and testing. The chamber is designed to allow water to enter the chamber, expand momentarily, separate from the air, move into the venting assembly and be released.
AGF specializes in the design and manufacture of inspector's test-and-drain valves, auxiliary drains, corrosion monitors, air-venting valves and accessories for the fire-sprinkler industry.
