A better way to maintain water level


The BROWN WEIGHT VALVES are spring loaded, naturally closed valves. When water is needed, the weight pulls down on the arm, providing leverage to open the valve. The solid weight is slightly lighter than water so when the water trough is full the weight floats, closing the valve.



The WEIGHT VALVE uses a spring loaded, naturally closed water valve.  When the water level goes down the weight on the arm pushes the valve open.  The weight is made of a durable plastic that is slightly less dense than water.  As the trough fills the weight floats up with the water level until the trough is full, allowing the valve to close.



This video is of the Brown Weight Valve being used in an actual environment where it is controlling the level of water in large water tanks for a car wash.

    Where can I buy one of these valves?
    I live in Minnesota and would like one I can mount under water and with the frost valve attachment.

    I have cattle and horses so may be interested in several of them.
    Tanks ranging from 100-300 gallons.
