ARI AIRVALVE BARAK (COMBI - 10 BAR)

ARI AIRVALVE BARAK (COMBI - 10 BAR)

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.
