The slide valve will have to be made with no lap, and roust be worked by an eccentric keyed on the shaft. In large engines where expansion valves are used, they could be set so as to cut off the steam to the end of the stroke, as the slide valve would be open to the full length of the stroke. The piston valves would also act as a throttle valve, and could be worked easily.
