AVK COMBINATION AIR VALVE, PN 16

For water, reinforced polyamide, DN12-50

Combination air valve for water and neutral liquids to max. 60°C (temporarily up to 90°C)

AVK combination air valves are combined air release and air and vacuum valves. The air release function releases accumulated air from the system while it is under pressure. The air and vacuum function discharges and admits large volumes of air during the filling or draining of pipelines. The valve will open to relieve negative pressures whenever water column separation occurs. The body and all operating parts are made of specially selected corrosion-resistant materials.

Variant 701/40-010
Connection: External BSP Thread
DN: DN12 - DN50
PN: PN 16

Features

  • Orifice sizes: DN 12 and 19: Air and vacuum 100 mm², automatic 8 mm². DN 25: Air and vacuum 100 mm², automatic 8 mm². DN 50: Air and vacuum 804 mm², automatic 12 mm².
  • The enlarged orifice is less exposed to obstruction by debris
  • The orifice in the automatic valve releases small volumes of air at high flow rates when the line is under pressure
  • The valve’s rolling seal mechanism design is less sensitive to different pressures than a direct float seal, thus enabling a one size orifice for a wide pressure range
  • Body of high-strength composite material
  • All operating parts of corrosion-resistant materials
  • Very low weight
  • A discharge outlet enables removal of excess fluids
  • With BSP thread connection
  • Working pressure range: 0.2 – 16 bar
  • WRAS approved product - certifcate avaliable upon request.
