Netafim DG-10 & D-040 Combination Air Valves

Description

The DG-10 & D-040 Combination air valves have similar features but they are made of different materials. The DG-10 is rated to 10 bar and the D-040 is rated to 16 bar.

Both models feature a combination air-release valve and an air-vacuum valve. The air-release component of the valves is designed to automatically release small pockets of air as they accumulate at local high points along a pipeline when the pipeline or piping system is full and operating under pressure. The air-vacuum component was designed to automatically discharge or admit large volumes of air during filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs

Applications

D-040 Applications

  • Pump stations: after the pump and after the check valve
  • Downstreem (after) and upstreem (before) shut-off valve
  • After deep-well pump
  • On long water supply lines
  • At peaks alon the line
  • At the end of lines
  • Before water meter
  • On strainers and filters

DG-10 Applications

  • Downstreem (after) and upstreem (before) shut-off valve
  • On long water supply lines
  • At peaks alon the line
  • At the end of lines
  • Before water meter
  • On strainers and filters
Features and Benefits
  • Light, simple and reliable structure
  • The valve prevents premature closing by discharging air at high velocity, exceeding 11 psi differential pressure
  • The orifice of the automatic continuous acting valve is larger than in any other air release valve of it's kind, therefore it discharges air at higher flow rates
  • The size of the automatic opening reduces the the possibility of obstruction by debris
  • The valve design features a rolling seal mechanism which is less sensitive to pressure differentials than a direct float seal. It accomplishes this by having a comparably large opening for a wide pressure range (up to 16 bar)
  • The body is made of high strength plastic, and all operating parts are made of specially selected corrosion resistant materials
  • Due to its light weight, the valve may be installed on plastic piping systems, as well as other lightweight piping
  • A threaded drainage outlet enables removal of excess fluids
  • The float is made for low sealing pressure (DG-10)
