An apparatus and a method of controlling flow communication with an apparatus are disclosed. The apparatus includes a flow communicator, a flow control member, an uphole-disposed flow interference effector uphole of the flow communicator, and a downhole-disposed flow interference effector downhole of the flow communicator. While each of the uphole-disposed flow interference effector and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, the flow communicator is closed. Displacement of the flow control member, relative to the flow communicator, in the downhole direction, opens the flow communicator. While there is an absence of occlusion of the second uphole-disposed flow interference-effecting member of the uphole-disposed flow interference effector, the flow control member is disposable, relative to the flow communicator, such that each one of the second-uphole disposed flow interference-effecting member and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, such that the flow communicator is closed.
