D-070P | 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 volumesof 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: 0.2 – 16 bar.
• Maximum operating temperature: 60°C.
• Maximum intermittent temperature: 90° C.
• For standard installation on water systems when the pipeline diameter is 8″ or greater and for all pipeline diameters when the slope of the pipeline is greater than 2%-3%.
