Abstract
A fluid supply component for a replaceable fluid supply may include a channel fluidically coupled to a pliable fluid supply bag; a ball housed within the channel; and a gasket to prevent movement of the ball into the fluid supply bag; wherein the valve prevents fluid from entering the fluid supply bag while the fluid supply bag imparts a negative fluidic pressure.
