摘要：
An animal watering valve that includes a housing having an internal bore having an upstream inlet and a downstream outlet. The housing includes a downstream guard and an upstream cap. The valve is actuated by deflecting a valve stem, located in the bore and accessible by the animal, to open a valve within the housing. The valve may be located in a valve cartridge retainable in the housing in a snap-fit manner. A bite-resistant shield cooperates with the valve stem to act as a barrier that prevents an animal from forcing materials between the valve stem and the guard and lodging the valve stem in its deflected or actuated position.
