Fill valve assembly for filler device and associated method of use

1. A fill valve assembly for use in association with a filler device, comprising:

a vent tube, a valve housing, a valve sleeve, and a seal member;

wherein the vent tube comprises an upper venting aperture, a lower venting aperture, an intermediate region having a lower displacement stop member having an annular upper surface, wherein the lower displacement stop member comprises an outer diameter greater than an outer diameter of the vent tube positioned immediately below the lower displacement stop member, and wherein the vent tube is positioned at least partially within the valve housing, and the valve sleeve:

wherein the valve housing is in communication with a filler device;

wherein the valve sleeve is positioned at least partially within the valve housing;

wherein the seal member is positioned within the valve housing;

wherein the fill valve assembly is positionable among a closed position, a first open position, a second open position, and a clean-in-place position;

wherein when the fill valve assembly is in a first open position, the seal member contacts an upper wall of the valve housing, and when the fill valve assembly is in a second open position, the seal member contacts the lower displacement stop member of the vent tube; and

wherein the seal member is configured such that moving the valve sleeve relative to the valve housing causes the seal member to displace upwardly relative to the vent tube and the displacement stop member from the second open position to the first open position.
