D-040 V / I | Combination Air Valve for Industry

Descripción

Características principales

• Working pressure range:
  • D-040 PA, St. St., PVDF, and Duplex: 0.2 - 16 bar
  • D-040 PP: 0.2 - 10 bar
• Testing pressure: 1.5 times the maximum 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.

• Reliable operation reduces water hammer incidents.
• Dynamic design allows for high capacity air discharge while preventing premature closure.
• Lightweight, small dimensions, simple and reliable structure.
• The discharge outlet enables the connection of a vent/drain pipe
• The large size of the automatic air release orifice relative to the air valve body:
  • Discharges air at high flow rates.
  • Lessens the danger of its obstruction by debris.
  • Utilizes the rolling seal mechanism, making it less sensitive to pressure differential than a direct float seal.
• Due to its light weight, the valve may be installed on plastic piping systems, as well as other lightweight piping systems.
