Descripción

The D-070-P Dynamic Combination Air 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.

Características principales

  • Working pressure: 0.2 - 10 bar.
  • 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.

  • Prevents slam and reduces water surges in the air valve and the pipeline.
  • Prevents the intrusion of debris and contaminants into the system.
  • Valve body and interior components are made from composite materials and are corrosion-resistant.
  • Valve is lightweight and small for easy installation; its operation simple and reliable.
  • Built-in connection at the outlet for surplus water drainage.
  • Smooth and gradual closing unaffected by water flow.
  • Extremely quiet closing.
  • Automatic air release component releases large quantities of air without becoming obstructed.

Selección de la válvula

  • Sizes: 2” , 3" threaded or flanged

Options:

D-070-P I
One-way valve intakes air only, without allowing air discharge.

D-070-P T
Valve has a flushing tap for flushing both the valve and the pipeline.

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.
