1. A valve for use in a hanger body of a well system, the valve comprising:
a valve body, the valve body configured for insertion into the hanger body in an axial direction and comprising an exterior surface;
a first segment of the exterior surface being configured with a helical thread to engage a counter-threaded portion of a tubing hanger body;
a second segment of the exterior surface being configured as an essentially circumferential groove to accommodate an essentially toroidal sealing member;
plural discrete stop members circumferentially arranged on the valve body and configured to control an extent of the insertion of the valve body into the hanger body and thereby preclude threads of the counter-threaded portion of a tubing hanger body from affecting the essentially toroidal sealing member.
