Abstract
A valve operating on hydraulic pressure for the control of water being deposited onto evaporative pads located on a cool tower. The valve utilizes water flow to fill a basin or tank which is slowly being drained. When the tank is empty, a valve is opened that releases water to the evaporative cooling pads and also to the tank; when the tank is filled, the valve closes permitting the tank to slowly drain and repeat the cycle.
