Abstract:
A fracture treatment check valve is disclosed. An illustrative embodiment of the fracture treatment check valve includes a valve housing including a valve housing wall defining a valve housing interior. A valve housing inlet is provided in the valve housing interior. At least one port opening having at least one beveled flow surface extends through the valve housing wall in spaced-apart relationship with respect to the valve housing inlet. A ball seat extends from the valve housing wall into the valve housing interior between the valve housing inlet and the at least one port opening. A valve ball is provided in the valve housing interior and positional between a first position in which the valve ball seats against the ball seat and a second position in which the valve ball disengages the ball seat and establishes fluid communication between the valve housing inlet and the at least one port opening. A valve spring is provided in the valve housing interior and normally biases the valve ball in the first position.
