Product Description


Product Information

The DG-10 combination air valve has the features of both an air release valve and an air & vacuum valve. The air release component of the combination air valve was designed to automatically release small pockets of air into the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component was designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

Product Features

  • Combines the features of both an air & vacuum valve and an air release valve.
  • Triple function:
    • Air & vacuum component discharges large volumes of air during the filling of the system.
    • Air & vacuum component admits large volumes of air during drainage and at water column separation.
    • The air release component releases entrapped air in pressurized systems.
  • Dynamic design allows for high-velocity air discharge while preventing premature closure.
  • Innovative rolling seal mechanism.
  • Available in sizes: 3/4", 1", 2" threaded male connections, NPT or BSPT.

Application Range

  • Working pressure range: 0.1-10 bar.
  • Maximum operating temperature: 60°C.
  • Maximum intermittent temperature: 90° C.
  • For installation:
    • At pump stations.
    • Downstream and upstream of shut-off valves.
    • After deep-well pumps.
    • On long constant-sloped pipeline segments.
    • At peaks along the pipeline and at peaks relative to the hydraulic gradient.
    • Additional protective shell for anti-vandalism/theft applications.
