A valve comprising a base plate defining an inlet and outlet passageway. A cover plate is disposed on the base plate and defines a first and second channel. A pressure plate is disposed on the base plate and includes a first anchoring portion, a first sealing portion, and a first biasing portion connecting the first anchoring portion and the first sealing portion. Furthermore, a suction plate is disposed on the base plate and includes a second anchoring portion, a second sealing portion, and a second biasing portion connecting the second anchoring portion to the second sealing portion. The valve is movable between a first configuration, where the first sealing portion is distal to first channel and the second sealing portion is proximal to inlet passageway, and a second configuration, in which the first sealing portion is proximal to first channel, and second sealing portion is distal to inlet passageway.
