Abstract
In some examples, an apparatus can include a pawl including an anti-rotation surface and a spring, and a valve housing including a wedge, where the spring biases the pawl to a first position in response to the valve housing being at a closed position such that the wedge of the valve housing contacts the anti-rotation surface of the pawl to prevent rotation of the valve housing at the first position of the pawl.
