Abstract
The present disclosure relates to a bidirectional valve design that provides for more rapid deflations/evacuation of fluid flow and in one example includes a valve body, a spindle piston movably coupled in a bore of the valve body and an electronically controllable motor that moves the spindle valve between a fluid evacuation position and a fluid fill position. In one example, the spindle piston includes piston structures on ends of a threaded rod. In another example, a mattress system is disclosed that employs the valve and a fluid source to provide quick evacuation of air from a patient support. In another example, the valve is coupled to an alternating pressure block valve which is then coupled to a patient support.
