While Drainer NLD Series removes liquids from pressurized air or gas systems, Venter NAV Series removes air and other gases from pressurized liquid systems. Both provide automatic, positive shutoff and proper seating under all operating conditions and instantly adjust to variations in flow and pressure. Offered in ½ x ½ in. and ¾ x ½ in. sizes with NPT connections, corrosion- and freeze-resistant valves are rated for pressures to 400 psig and temperatures to 500°F.
