The D-070 Combination Dynamic Air Valve is a unique valve operating without a float, utilizing the rolling diaphragm principle. This unique structure allows the dynamic valves to discharge air from the water system in a controlled and gradual manner, preventing slam and local up-surges. When vacuum occurs , the valves fast reaction will draw in large volumes of air into the water system, impeding down-surges and, consequently, all pressure surges in the line. The valves are normally closed when the line is not operating, thus preventing the infiltration of foreign particles and insects into the water system.

• Pumping stations, deep wells, and distribution lines.
• Systems that suffer from slam and local and system surges.
• Sites that require a combination of means to reduce water hammer or surges.
• Sites that require an air valve with a low profile due to lack of space.
