Valve for gravel packing a wellbore

A downhole tool, comprising:

• a housing comprising a screen;
• an inner tubular member positioned radially-inward from the housing such that an annulus is formed therebetween, wherein a first opening is formed radially-through the inner tubular member;
• and
• a valve system positioned within the annulus, wherein the valve system comprises:
• an intermediate tubular member having a second opening formed radially-therethrough;
• a first valve positioned at least partially in the intermediate tubular member, wherein the first valve has an axial bore formed at least partially therethrough, and wherein a third opening is formed radially-through the first valve;
• a flow control device positioned within the axial bore;
• and
• a first degradable member configured to at least partially degrade in response to contact with a first fluid,
• wherein the valve system has a first position where the first valve allows a flow within the housing, a second position where the first valve directs at least a portion of the flow through the flow control device, and a third position stopping flow through the flow control device.

A method for gravel packing a wellbore, comprising:

• degrading a degradable member in a downhole tool, wherein the downhole tool comprises a screen, a valve system, and a flow control device, and wherein the valve system comprises a first valve;
• moving the first valve in response to the degradable member at least partially degrading;
• and
• directing at least a portion of a fluid that flows through the screen to flow through the flow control device with the first valve after the first valve moves.
