Abstract
A pilot valve actuator for use with a hydrant valve has a pilot valve and a removable actuator. The pilot valve blocks communication between a primary hydrant chamber and a piston chamber when in a closed position. Under pressure, the actuator opens the pilot valve against its biasing force permitting the flow of fluid between the hydrant chamber and the piston chamber. The pilot valve is permanently attached to the hydrant valve. The actuator is removable from the pilot valve by a quick disconnect mechanism permitting storage of the actuator remote from the hydrant valve.
