ABSTRACT:
A valve apparatus and method for controlling flow of water to an end gun of a pivot irrigation apparatus. An actuator mechanism for the valve apparatus includes a horizontally mounted, downwardly extended contact bar interconnected by a mechanical linkage to the valve. Contact posts are selectively positioned at preselected intervals along the path of travel of the pivot irrigation apparatus at locations where they will be engaged by the contact bar to rotate the same. The rotational movement of the contact bar is translated by the mechanical linkage into a corresponding rotation of the valve.
