ABSTRACT:
A low toggle force poultry watering valve includes a body having a passageway therethrough within inlet and outlet ends. A step is within the passageway. Two cylindrical regions of differing diameter define the passageway upstream of the step with the region of lesser diameter being closer to the step and facing a passageway inlet. A ball for closing the valve rests against a seat defined by the region of transition between the cylindrical areas of differing diameter. A valve operating stem displaces the ball from contact with the seat and thereby opens the valve upon displacement of the stem by poultry.
