Abstract
The present specification is directed to a valve that has an orifice closing member adjacent to an orifice through which fluid can flow, a displacement member having a first portion and a second portion, where the first portion is adjacent to the orifice closing member when the valve is in an open position, a first magnet and a second magnet where the first and second magnets are sufficiently proximate to the displacement member to exert a magnetic force on the displacement member, and an actuator for generating a magnetic field to move the displacement member toward the first magnet, cause the first portion to press against the orifice closing member, and cause the orifice closing member to close the orifice.
