Description

The DG-70 combination dynamic air valve is a unique valve, operating without a float and utilizing the rolling diaphragm principle. 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.

Product Features

  • A unique valve, operating without a float and utilizing the rolling diaphragm principle.
  • Valve discharges air from the water system in a controlled and gradual manner, thus preventing slam and local up-surges
  • Normally closed air & vacuum orifice prevents the intrusion of debris and contaminants into the system.
  • Smooth and gradual closing unaffected by water flow.
  • Available in sizes:
    • 2”, 3" M1, threaded or flanged BSP/NPT.
    • 4” M2 flanged only.

Materials and Corrosion Protection

  • Valve body and internal components are made from composite materials and are corrosion-resistant.
  • Air release body made of high strength composite material; all operating parts are made corrosion- resistant materials.
  • Optional: One-way D-070 P-I valve admits air only, without allowing air discharge.

Application Range

  • Working pressure: 0.2 - 10 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%.
