The valve only needs pressure in the water line filling the water trough to operate. The advantage of the valve is that it provides a constant water level.

The principle of operation of the float valve is exactly the same as that of the valves in the toilet tanks. Unlike electrically operated tank filling systems, the float valve is completely mechanical.

The angle of the valve arm can be adjusted, so the required water level can be precisely set. With 1/2 inch water connection and replaceable strong plastic float.

Threading: External thread (ET).

Material: Copper.

The valve is placed on the trough, with a metal sheet cover, to prevent the access by the animals!
