Abstract
An injection valve for introducing fluids into a subsurface environment includes a valve housing including a conduit having an inlet and an outlet. A valve seat member is arranged in the valve housing. The valve seat member includes an outlet portion and a valve seat. An anti-rotation dart is arranged in the valve housing. The anti-rotation dart includes a valve element that selectively extends into the outlet portion and is engageable with the valve seat. An anti-rotation feature is provided on at least one of the valve seat and the anti-rotation dart. The anti-rotation feature constrains rotation of the anti-rotation dart relative to the valve seat.
