A valve for a bladder control device including an elongate housing having a valve seat disposed therein. A stopper is also disposed within the housing and is moveable between a first position in which the stopper engages the valve seat and a second position wherein the stopper is moved distally of the valve seat. A tension spring can be connected to the stopper to biases the stopper toward the valve seat. A lumen is defined through the housing having a first portion disposed distally of the valve seat having a diameter approximately equal to a diameter of the stopper. A second portion of the lumen disposed distally of the first portion has a greater diameter than the first portion of the lumen. Yet a third portion of the lumen disposed distally of the second portion has a diameter less than that of the first portion.
