Description

The D-060 Combination Air Valve has the features of both an air release valve and an air & vacuum valve.
The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure.
The air & vacuum component is 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.

Main Features

  • Working pressure range: 0.2 - 16 bar
  • Testing pressure for the air valve is 1.5 times its working pressure.
  • Maximum working temperature: 60° C.
  • Maximum intermittent temperature: 90° C.

Note: For applications requiring a working temperature above the maximum stated or below 50 C., please consult first with the A.R.I. Applications Engineering Dept.

  • All main flow cross-sections are equal or greater than the nominal port area.
  • Aerodynamic design enables high flow rates of air both at intake and at discharge.
  • Reliable operation reduces water hammer incidents.
  • Dynamic design allows for high capacity air discharge while preventing premature closure.
  • Screen protected outlet.
  • The upper screen is protected with a protective cover.

Air Release Component

  • Body made of high strength materials.
  • All operating parts are made of specially selected corrosion- resistant materials.
  • Large size air release orifice:
    • Dramatically reduces the possibility of obstruction by debris.
    • Discharges high air flow rates.
    • One size orifice for a wide pressure range, achieved by utilizing the rolling seal mechanism.

Valve Selection

  • Size Range: 2”- 10”
  • These valves are manufactured with flanged ends to meet any requested standard.
  • The 1", 2” valves are also available with a threaded BSP or NPT connection.
  • The D-060-I combination air valve (2” – 4” only) can be supplied with an optional In-only check valve attachment, allowing for air intake only; prevents air discharge.
  • The D-060-V combination air valve (2” – 4” only) can be supplied with an optional Out-only check valve attachment, allowing for air discharge only; prevents air intake.
  • The air release component and the air & vacuum component are available as separate units.

Note

For best suitability, it is recommended to send the fluid chemical properties along with the valve request.
Upon ordering, please specify: model, size, working pressure, thread and flange standard and type of liquid.
