Abstract
A filler valve assembly that includes a first housing member with an elongated hollow filler tube secured thereto, the filler tube having an outlet through which liquid exits when filling containers. A second housing member having secured thereto an elongated piston with an enlarged end portion is provided so that the elongated piston is disposed interior of the filler tube. The piston is axially moveable with respect to the filler tube to move the enlarged portion of the piston from a first, closed position to a second, open position. When in the closed position, a substantially liquid-tight seal is formed between the outlet of the filler tube and the enlarged portion of the piston, both the outlet and the enlarged portion being formed of a metal so that the seal is formed solely by metal-to-metal contact.
