Abstract
In a bi-directional valve control system, a differential, bi-directional valve seating member for operation at a seating surface wherein the seating member comprises a multi-membered disk formed of at least first and second contiguous disk elements. The first disk element is formed of flexible material which is capable of primary deformation in response to fluid flow along a flow line direction corresponding to second-to-first disk orientation. This first disk element is configured in size and shape to increase seating contact at the seating surface by flow-pressure assist principles which cause the primary deformation response. The second disk element is formed of flexible material which when combined with the first disk element is less capable of deforming than the independent deformation first disk element. This second disk element resists the primary deformation response with respect to fluid flow along the opposing flow line from first-to-second disk element orientation. The resistance against primary deformation of the first disk element provides enhanced seating contact by pressure assist principles.
