D-070 | Dynamic Combination Air Valve

This unique structure allows the dynamic air valve to discharge air from the water system in a controlled and gradual manner, thus preventing slam and local up-surges. When vacuum (down-surge) occurs, the valve reacts quickly to admit large volumes of air into the water system, thus impeding down-surges and, consequently, all pressure surges in the line. The air & vacuum component of the dynamic air valve is normally closed when the line is not operating, thus preventing the infiltration of debris and insects into the water system.

Application Range

  • Working pressure range: 0.2-16 bar.
  • Maximum operating temperature: 60°C.
  • Maximum intermittent temperature: 90° C.
  • For pump stations, deep wells and distribution lines, systems prone to slam and local and system surges, sites that require a combination of means to reduce water hammer or surges and sites that require an air valve with a low profile due to lack of space.
