ABSTRACT:
A demand type animal watering valve that is operable by animal mouth actuation of an exposed valve stem. The bulk of the valve including the valve body is comprised of a relatively inexpensive and relatively soft composition that if unprotected would be potentially chewable by the animal when watering. For protecting the soft material at least about the mouth engageable portion of the valve there is provided a mouthguard sleeve of significantly harder chew-resistant metal such as stainless steel. The sleeve is secured to the relatively soft body material in a manner preventing removal separation of the sleeve by the animal. Also disclosed are optional embodiments of a filter screen/orifice plug unit removably insertable in the valve. One embodiment includes a fine mesh screen secured to the inlet side of the plug in which are disposed a plurality of selectively openable parallel orifices for variably setting the desired flow rate of the valve.
