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 The float is the only moving part. Simple design, with no hinges or levers. Tight Sealing The grounded float and rubber valve seat prevent leakage (VAS series, VA series). The -precision-grounded float and 3-point seating prevent leakage (VS1A series). Operation Animations Application Areas For use where the discharge of large quantities of initial air is required. Once the valve closes, it remains closed even if air enters. Also install an automatic air vent if it is necessary to discharge air during operation. Main Applications Water lifting pumps, water transport lines, water storage tanks, hot water tanks, holding tanks for liquids. Water, hot water – VAS series, VA series Water, hot water and other non-toxic or non-flammable liquids – VS1A series
