Apr 03, 2007 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.

Feb 08, 2005 Available for 2, 3, and 4 in. floor drains, Floor-Guard® operates like check valve to seal off water back-up caused by overloaded sewers. Water flows normally through drain until sewer begins to back up; then Floor-Guard float rises to seal off drain opening until water recedes. Unit requires only screwdriver for installation, and once in place, can prevent property damage. Flood-Guard® is also available in stand pipe model for handling extreme, extended pressure.
