Patent ID: 8573254

Claim:
A flow control device for a flow control manifold assembly having a manifold body, the flow control device comprising: a sleeve monolithically formed of an elastomeric material and including a cylindrical outer surface, a sleeve axis of rotation concentric with the cylindrical outer surface, a through hole oriented transverse to the sleeve axis of rotation, a first raised portion that encircles the sleeve and is shaped to provide a seal between the sleeve and the manifold body, and a first interface shaped to connect the sleeve to an actuating member, wherein the first interface is configured as a female coupler; and the actuating member including a second interface shaped to interface with the first interface, wherein the second interface is configured as a male coupler, the first and second interfaces shaped to transfer rotation of the actuating member about the sleeve axis of rotation to the sleeve to reorient the through hole relative to a fluid passage of the manifold body; wherein the second interface extends within the sleeve along the sleeve axis of rotation to a position transverse to or beyond the through hole when the actuating member is connected to the sleeve; and wherein the first and second interfaces accommodate the through hole such that the through hole is not in fluid communication with the first and second interfaces.
