Abstract: An animal watering valve includes a housing having an upstream end, a downstream end, a bore extending therebetween, a valve element and a valve actuator located at least in part in the bore, and a plug disposed within the bore upstream of the valve element. The plug includes a lattice structure extending along a length of the plug. The valve element may be a diaphragm disposed within the bore to separate the bore into upstream and downstream portions. The valve actuator has a stem with a stem body extending downstream from a stem head and through an outlet of the housing. The diaphragm includes a sealing surface with first and second annular ridges and a groove disposed therebetween. A stem hat having a cap and disk is coupled to a downstream end of the stem. The disk extends radially from the stem at a location upstream of the outlet.
