1. A method, comprising:
- selectively moving a friction member between a first radial position and a second radial position relative to a body of a valve, wherein the friction member is configured to move from the first radial position to the second radial position in response to a first hydraulic force provided by a running tool to secure the valve in a straight portion of a bore only with friction, and the friction member is configured to move away from the second radial position toward the first radial position to release the valve from the straight portion of the bore.

Abstract
A system includes a back pressure valve. The back pressure valve includes a body, a plunger disposed internal to the body, and a friction member disposed about the exterior of the body. The friction member is configured to expand radially to contact an internal surface of a bore. A method includes disposing a back pressure valve into a straight bore and expanding a friction member of the back pressure valve radially into contact with an internal surface of the straight bore.
