Valve system

A pump, comprising:

• a valve comprising:
• a base plate defining an inlet passageway and an outlet passageway, the inlet passageway included in a suction portion of the valve and the outlet passageway included in a pressure portion of the valve,
• a cover plate disposed over the base plate, the cover plate defining a first channel in the pressure portion and a second channel in the suction portion,
• a pressure plate disposed on the base plate in the pressure portion, the pressure plate including a first anchoring portion, a first sealing portion, and a first biasing portion connecting the first anchoring portion and the first sealing portion,
• a suction plate disposed on the base plate in the suction portion, the suction plate including a second anchoring portion, a second sealing portion, and a second biasing portion connecting the second anchoring portion and the second sealing portion,
• a first sealing member positioned proximal to an outlet of the first channel, the first sealing member configured to form a first fluid tight seal with the first sealing portion in a second configuration, and
• a second sealing member positioned at an inlet of the inlet passageway within the base plate, the second sealing member configured to form a second fluid tight seal with the second sealing portion in a first configuration;
• and
• a membrane disposed on the cover plate, the membrane and the cover plate defining a chamber therebetween, the pressure portion and the suction portion in fluidic communication through the first channel and the second channel via the chamber,
• wherein the pump is movable between the first configuration in which the membrane is proximal to the cover plate, the first sealing portion of the pressure plate is distal to the first channel such that a fluid is expelled from the chamber into the outlet passageway through the first channel and the second sealing portion of the suction plate is proximal to the inlet passageway and fluidly seals the inlet passageway, and the second configuration in which the membrane is distal to the cover plate, the first sealing portion is proximal to the first channel and fluidly seals the first channel, and the second sealing portion is distal to the inlet passageway such that the fluid is drawn into the chamber from the inlet passageway via the second channel.
