In one embodiment, a sprinkler valve includes an actuator member that is rotatably disposed within a sprinkler head and restricted from vertical movement. The inside of the actuator member includes a helical groove within an inner cavity. A plunger at least partially fits within the actuator member's inner cavity and further includes a thread that mates with the helical groove of the actuator member. As the actuator member is rotated by a user, its helical groove causes the plunger to move downwards toward the top of a tube or water passage. If fully extended downward, the flat portion of the plunger fully covers and seals the top of the tube, preventing water from escaping from the sprinkler.
