Abstract
Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float. The moveable float can form a fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and a flow opening when the moveable float is at least partially decoupled from the outlet base. Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.
