Abstract

A filling valve apparatus having a body portion with an inner wall terminating at an aperture to define a sealing seat. The inner wall extends below the seat to define a trap for a fluid. A cage extends from the body portion with the cage having an inner wall mating with the inner wall of the body portion to define a continuous inner surface. A stem, having a seal, includes an outer surface that is complementary in configuration to the continuous inner surface to define a smooth passageway for the fluid as the fluid is directed into the container thereby ensuring a laminar flow of the fluid between the inner and outer surfaces and into the container. The filling valve apparatus also includes a pre-assembled body portion, valve assembly, cap assembly, lower vent tube assembly, and snift valve.
