ABSTRACT:
A water control valve particularly suited for use with poultry watering apparatus having a deformable rubber sleeve lining the interior of the valve housing. A pair of piston members are arranged to pinch the sleeve and thus cut off the flow through the valve in response to a cross member attached to a control lever alternately urging each of the pistons into the housing.
