ABSTRACT:
A poultry watering cup valve for controlling the flow of water from a water feed line to a poultry watering cup includes, generally, a substantially hollow valve housing extending from the watering cup for engaging the water feed line, and an improved valve seal positioned within the feed line and over the end of the valve housing opposite the watering cup. A shaft extending through the valve housing supports the valve seal adjacent a valve inlet aperture. In one preferred form, the valve seal includes an integral O-ring which can prevent fluid flow from the feed line through the valve inlet aperture. In another preferred form, the valve seal is provided a second integral O-ring which, like the first O-ring, can also prevent fluid flow from the feed line through the valve inlet aperture.
