Abstract

A grade vent valve assembly (20) includes a float (42) moveable between a lowered position and a raised position. A lever 48 is coupled to the float 42 at a first end (58) of the lever (48). The lever (48) pivots about a fulcrum spaced from the first end (58) in response to movement of the float (42) between the raised position and the lowered position. The lever (48) pivots between an open position when the float (42) is in the lowered position, and a sealing position when the float (42 )is in the raised position. The lever (48) seals an orifice (36) when in the sealing position to block fluid flow through the orifice (36).
