Abstract

A safety valve ( 114) can be disposed in a well bore ( 102) that is through a fluid-producing formation. The safety valve (114) can include a flow tube (204) that is allowed to move at least partially independent, or free, from a piston assembly (202) to avoid negative effects from forces on the flow tube (204) from a closing assembly (208), such as one including a flapper (211 ). For example, the flow tube (204) may not be required to be rigidly connected to a piston assembly (202) such that the flow tube (204) can move more than the piston assembly (202) moves. FIG. 2
