1. A system comprising:
a valve seat positionable in a rotary steerable drilling system and comprising a plurality of channels through which fluid can flow to control activation of three or more steering pads during operation of the rotary steerable drilling system; and
a steering valve positionable in the rotary steerable drilling system adjacent to the valve seat, wherein the steering valve can rotate relative to the valve seat to control a flow of fluid through the plurality of channels such that:
the three or more steering pads are activated and deactivated in a sequential order based on rotation of the steering valve relative to the valve seat;
each of the three or more steering pads are activated for more than or equal to 120° of rotation of the steering valve relative to the valve seat; and
the flow of fluid through the plurality of channels is blocked to all of the three or more steering pads at a specific orientation of the steering valve relative to the valve seat.
