Air drain VA series

condensatewaterautomatic

Rapid initial air vents feature a large orifice, allowing them to discharge large quantities of air in a short time. This makes them the ideal choice for removing air from water tanks and water supply pipes during startup. Once the initial air has been discharged, the valve will close and typically will not open again during normal operation. However, when pressure in the pipes falls to near or below atmospheric pressure, the valve will open once more. This allows air to enter, preventing vacuum conditions from forming within the pipes and allowing liquid to be easily passed downstream. Though rapid initial air vents are able to discharge large quantities of air quickly, once the valve closes, it will not open again as long as a pressure differential is maintained. If it is necessary to continuously discharge air during normal operation, please use this product together with an automatic air vent. Benefits and Features Automated Initial Air Discharge The large-size valve seat rapidly discharges initial air. The float responds with great sensitivity to condensate levels, automatically closing the valve and thereby eliminating the need for manual labor. Long Service Life Simple construction with no levers or hinges Only one moving part: the Free Float®. This eliminates concentrated wear and provides long service life. Tight Sealing Provides a tight, reliable seal Rapid Initial Air Vents (all series) Application Areas Rapid initial air vents are suitable for: instances where there is a need for the rapid discharge of air upon system startup processes which require expedited water supply water supply pipes, water tanks, water pumps (VAS, VA)
