The present invention is directed to a valve that has an orifice closingmember adjacent to an orifice through whichfluid can flow, a displacement member having a first portion and a secondportion, where the first portion is adjacent to the orificeclosing member when the valve is in an open position, a first magnet and asecond magnet where the first and second magnets aresufficiently proximate to the displacement member to exert a magnetic force onthe displacement member, and an actuator for generatinga magnetic field to move the displacement member toward the first magnet,cause the first portion to press against the orificeclosing member, and cause the orifice closing member to close the orifice.
